Dear [ Best Friend],
I hope this letter finds you in good spirits! I wanted to take the time to write and let you know how much I love and appreciate you in my life.
I can’t express how thankful I am to have a best friend like you. You have been there for me through all of the highs and lows, and it’s a blessing to have you in my life. I know that I can always rely on you to offer your support and advice. I’m so lucky to have such an amazing best friend like you!
I can’t wait until we can hang out again soon. I miss our conversations and jokes, and I look forward to more fun times together soon. Until then, just know that I am thinking of you and sending all my love.
Yours always,
[Best Friend]
