I can't continue

When you have few extra pounds and your crush makes fun of you, you can't just handle it in. You start starving yourself and then you start cutting yourself, but nothing helps. And then you are on the other side of the game...

"I just can't! " I said giving up on everything. "Of course, you can't! If I was you I won't can." He brust out of laughing. Tears forming in my eyes, I don't know if I can keep them....

"Now I'm yours and now I'm your problem." I said looking at the ceilling. "I should have never done this. And I'll try my best, but you need to listen to me."

PS: I know it is clishe, but it is MY clishe.
