I'm sorry. I'm sorry that I'm not perfect like you! I"m sorry you have the WORST LIFE EVER. Oh, man. you're healthy, you have responsibilities, and family, too. Wow, sucks to be you..
 I'm sorry that YOU listened to those dumb rumors! I'm sorry you believed them.  I'm sorry that when people made fun of you, I defended you. I'm sorry you didn't do the same. I'm sorry you were never a good friend to me and I just put it aside. I'm sorry you're so self-obsessed and attention-starving. I'm sorry you think you're right all the time. I'm sorry you think you're so generous. I'm sorry you're prettier than me. I'm sorry you're more talented then me. I'm sorry you make me hate myself. I'm sorry I can never live up to your expectations. I'm sorry I cry everyday because of you.
I'm sorry you'll never get this letter. But most of all and overall, you should be sorry. But no, because you're never sorry. Because you're . . . you.
I'm sorry I ever thought you were my friend.
