1. Dear bestie,

I can’t believe you are 21 already. It feels like yesterday when you walked into the classroom in kindergarten, and our teacher made you sit beside me. I guess I have to thank Mrs. Palmer for bringing you into my life. Thank you for staying by my side for all these years.
We have survived through some difficult times together, supporting and inspiring each other every time we were about to give up. I wish we can continue being each other’s biggest supporters for the rest of our lives. I love you so much, and you are the most amazing best friend I could ever ask for. May your special day be filled with happiness, warmth, and love. Happy birthday!

Your bestie,

2. Dear Name,

As you already know, I am not the best at expressing my feelings. But since it’s your birthday, I wanted to write you a letter because you deserve the most extraordinary things in life. You are a beautiful soul, kind and sweet, who always thinks of others before herself. Your selflessness and innocence inspire me to become a better person every day. If Spring were a person, it would be you. I don’t know what I would do without you. Thank you for having my back, for accepting me the way I am, for never sugar-coating your words, and for loving me. I promise I will do the same.

Cheers to our special friendship, and here’s to more!

Love you, always.

3. Dearest friend,

Remember your 10th birthday party? We gorged on chocolates and cakes and danced to our favorite songs all day long. Your parents even took us to the movies and bought us so much popcorn and cola. It has been twelve years since then, and you are still that crazy, bubbly person. There is never a dull moment with you. We have made so many memories together, and I hope we get to make more. After all, we still have a lot left to do on our bucket list. Let’s achieve all our goals together!

I pray to God for your good health, great success, and happy life. Wish you a happy birthday!

4. Dear Name,

I know you have an important job interview this week, and you have been quite stressed about it. It’s normal to feel scared, but don’t underestimate yourself or doubt your merit. You are one of the most hardworking and dedicated people I know who always try their best. It has been my honor to stay by your side through all your ups and downs.

You are deserving of this job, so don’t lose hope. Even if it doesn’t work out, bigger and better opportunities will come your way. I am incredibly proud of you and glad that you are my best friend. Best of luck!

Your best friend,

5. Hey best friend,

A little birdie told me that you are having a rough day, so I am here to cheer you up. I know these tough times are hard to deal with, but you are a strong, kind, and magnificent person, capable of winning against all odds. Don’t forget to take care of yourself and focus on your well-being. Others’ opinions and nasty comments don’t matter because you are talented and fabulous in your way. And I am here for you always, so don’t bottle up your feelings when you have me to rant to. I may not have all the answers, but I will bring ice cream, cookies, and a shoulder to cry on.

So turn your frown upside down and show everyone how brilliant you are. I love you!

Your friend,

6. Dear bestie,

It’s exam week, and since I know how deep you fall into studying mode, I am here to remind you to take care of yourself. No matter how important studies are, take some breaks in between to relax. Keep yourself hydrated, and by that, I mean water, not coffee.

I know coffee helps to stay awake at night but drinking too much is not good for you. It will stop you from having a good night’s sleep. Eat healthy foods and don’t even think about missing meals. Most importantly, you will do great, so don’t panic too much.

If you need any help, you can always reach out to me. We can study together and make flashcards to memorize. All the best!

With love,

Emotional Letter For Best Friend

It’s not easy to talk about your feelings out loud, even with your best friends. But an emotional letter is an excellent way of articulating your emotions, and it’s also thoughtful.

7. Dear Name,

When I look back at all these years that we have spent together and how we met, I start believing in fate. We, becoming best friends, had to be the magic of destiny. No one understands me as well as you do. You can catch the slightest changes in my mood, and I honestly feel you can read my mind. An incredible person, inside and out, you have given me the most significant life lessons that have made me the person I am today.

Thank you for being the most wonderful best friend anyone could ever ask for. I promise to support and cheer for you in every way possible. Let’s stay together forever!

With all my love,

8. To my dearest Name,

I don’t think I tell you enough about how much you mean to me. You have seen me in my worst times, and yet here you are, protecting and loving me every single day. You are my safe space, where I feel accepted and comfortable, even when my life falls apart. As someone who has only ever been in toxic relationships, you showed me what wonders a healthy relationship could do to a person. Today, I get the strength to live each day happily because of you. You are my rock, and I hope I make you as proud as I am of you.

I wish I could say this to you face-to-face, but we both know the tears won’t stop. I hope you get to experience all the beautiful things in life, and I hope you will take me along.

Lots of love,

9. To my sweetest Name,

Remember that time we read about soulmates and thought it was all fantasy? But when I think of us, I think it makes a lot of sense. It’s not easy to find people in your life who you can trust unconditionally, who you can count on, and never have to worry about getting hurt. You push me to become a better person and make me laugh even when things get complicated.

When I think about the future, I get worried at times. What if we are forced to move to different cities for college or work? Will we slowly drift apart and become fading memories? I don’t know what will happen, but when you make a silly face or say something funny, I realize we will stay best friends for a long time. Our bond is far stronger than distance or other adversities. Also, do you know that the red string of fate is unending?

Your soulmate,

‘Open When’ Letters For Best Friend


If your best friend is moving somewhere far or you want to give them little surprises when they least expect it, the ‘open when’ letters are an innovative way of showing your love. Give them some mystery through these kind of letters.

10. Open when you need a laugh

Hey bestie,

Is the new city giving you a hard time? Well, take a break and join me on a ride down memory lane. First stop, fifth-grade recess. Remember when I was trying to ride the swing and accidentally face-planted on the ground? I think my nose still hurts, but it sure gave you a good laugh then. It was also the day we became friends.

Also, that time we went to Kevin’s birthday party and had more cake on our faces and hair than our tummy? I even found the photo, so I am sending it to you. I know work is stressing you out but relax and don’t take life too seriously. Sit back and think about these memories for a good laugh.


11. Open when you feel lonely

Dear Name,

If you are opening this letter now, it means life isn’t being kind to you. If I was there with you, we could cuddle, watch your favorite movies, and scream our frustration away. But since I’m not, how about you put on the playlist we curated together and light those fragrant candles I gave you for your birthday. Also, have you eaten? Order a pizza and try to take your mind off all that’s bothering you. Most importantly, call me?


12. Open when you doubt yourself


I have been with you since we were in diapers. I had cheered for you when you won your first spelling bee contest, when you were the topper of our batch, when you got into the college of your dreams, and every other achievement. So believe me when I say that you are an incredible person and have worked immensely hard to reach this position. You are tenacious, determined, strong, and the most deserving person I know.

Don’t let anyone or anything make you believe that you cannot achieve greatness because that’s a lie. You can achieve anything if you set your mind to it. I believe in you.

Your cheerleader for life,

Pardon me for being embarrassing, but you are the sun to my moon, the yin to my yang, the Sherlock to my Watson, and every other iconic pop culture power couple. You are brilliant, hilarious, stunning, and the apple of my eye. Every moment spent with you is perfect, and I wouldn’t have it any other way.

I promise to binge-watch all your favorite shows, go to the mall and help you pick clothes, talk about your recent celebrity crushes, and give you my portion of french fries. French fries, Name! If this isn’t the biggest declaration of love, then I don’t know what is.

Forever yours,

15. Hey buddy,

I know things have not been easy recently but thank you for hanging out with me. You have always been so giving and kind, and trust me; I never take your thoughtfulness for granted. However, I realize that I should have shown my appreciation more often.

Thank you for being by my side through tough times, for accepting me for who I am, and for never asking for anything in return.

I hope to do the same for you and make you proud. Thank you for being my best friend.

With love,

16. Dear Name,

I want to thank you for taking the time to hear me out. You have no idea how much that means to me. I know the misunderstanding has caused you a lot of pain, and I am to blame for it. Thank you for being so forgiving, even though I don’t think I deserve it. I promise not to disappoint you again.

I hope we can go back to the way we were before. I know it will take time, but I will try my best to win back your trust. Thank you for the second chance, best friend.

Your friend,

17. Dear bestie,

I know I don’t say this enough but thank you for being you. You are the greatest friend I could ever ask for, and I feel God has sent you to me as my guardian angel. You always listen to my problems and try to help me in every way possible. You are always open-minded and accepting and never judge me for being the way I am. No one else can understand me the way you do, and I am so fortunate to have you in my life. Friendships like these come once in a lifetime, and I promise to cherish you forever.

Love you to the moon and back,

If you and your best friend haven’t seen each other for a long time and you are missing them, write them a letter to let them know about your feelings.

18. Dear Name,

It has been exactly one year, four months, and 24 days since I last saw you. Are you wondering how I know? Because I miss you so much, and I might have obsessively kept count to make myself feel better.

There’s so much we need to talk about. I need to show you all the new restaurants that have opened up in the area, and you need to tell me everything about your new place. You must have met many new people there, but you are not allowed to forget me, okay? I am your soul partner, and your parents love me, so there’s no way anyone can take my place.

Please come to visit me soon. I have so much gossip that I think I might burst.

Love you,

19. Sweetest Name,

I have been thinking about our childhood memories a lot. Mum discovered an old photo album while cleaning, and it has so many pictures of us. It’s incredible how fast time flies. It seems like yesterday we were writing on our scrapbooks, and talking about life goals and promises. We have spent practically every waking moment together ever since we met, and now it feels weird not being able to meet you whenever I want.

Sometimes I forget that you are not in the house next door, a window’s reach away. But I’m so proud of you for chasing your dreams and taking risks along the way. I hope you are taking care of yourself. And remember that I’m only a phone call away. I miss you terribly.

Love you,
