Dear new best friend,
Thank you for coming into my life. You couldn't have entered my life at a better time. We've only been friends for a short time, but it feels like a lifetime.
You taught me not everyone you come in contact with is your friend, and you should be mindful of who you let into your life. Thank you for helping me realize the truth about my ex-best friend. If it wasn't for you, I wouldn't have found out I had depression and needed to get help as soon as I could.
Thank you for always finding ways to make me laugh. Whenever I have one of my bad days, I can always count on you to make me feel better. I appreciate you and everything you've done for me thus far.
Thank you for taking time out of your day to talk to me every day and putting up with my constant mood swings; it means a lot. I'm sorry I'm so scared to get close to you because of what happened to me previously. I know I may not show it, mainly because I'm scared to do so, but I really do care about you.
I hope we're friends forever.
P.S. — I love you.
Love, your best friend
