Dear Best Friend,
I wish I had the right words to tell you how horrible I still feel about everything that has happened between us. I do wish I could turn back time, so I could stop myself from hurting you. You were my pride and joy, and I cannot imagine what my life would have been like if you never came into my life. I will always cherish our friendship and the memories we made together. I'm always proud of everything you accomplished, and I will always cheer you on. You really were the best thing that has ever happened to me. I just made a mistake that was beyond stupid, and I wish I could take it all back.
I know that every time you see me now, you think of all the memories that you would like more than ever to forget. I would like you to know that you did not deserve what I did to you at all. You are such an amazing person, inside and out, and you deserve so much better. I still cry myself to sleep every night because of what happened because I hate to see you hurting. Every time I see a picture of the two of us, I can't help but cry because I would give up the world to see you happy again. I took advantage of our friendship just because you were the first person to tell me that I was not what everyone else said I was, and that I was so much more than what others label me as. That was the worst thing I could possibly do to someone I care about. I just wish there was some way I could be able to help you get through this. I want you to heal, and I don't want you to suffer anymore. I want you to know that there is a light at the end of this dark tunnel.
I also understand the damage that has been done, and I do expect to be forgiven for what happened, as much as I want you to. You are not obligated to forgive me for any reason because this took a serious toll on our friendship, and I can see the damage that has been done. But I will let you know that I am trying my hardest to do better. I cannot let what has happened to us happen to someone else I become friends with, and I want to show you that I changed. I want to show you that I really want your trust back more than anything, and I'm trying my hardest to earn that. No one could ever have the same impact on me like you have, and I want to show you that I'm still worth it.
With love,
Your (best) friend that's trying to do better
