What a powerful ending. A sad piece, but the repetition works well and I like what you've done with it.
All the best, and take care,

I'd have to disagree about the repetition. I don't think it works here and it seems to break the flow. That's just my opinion though. May I make a suggestion for a different format/ structure?

"I'm sorry

for being so screwed up inside - broken
for finding it hard to trust
leaning on you, flinching away.

For not being supportive
being scared, awkward - worrying.

I'm sorry my skin's not smooth.

I'm sorry that I can't see you.
I'm afraid to call you.

I'm sorry she's better then me
but most of all I'm sorry you think you love me."

- I think some of the times when you say "for..." you could put it together to create some more structure. I also moved around some lines just to give you an idea. I don't think the lines of "being ugly" or "fat" work. But I liked how you said this: "I'm sorry my skin's not smooth". That is less cliche and more creative than saying "ugly" or "fat".

I think it would be more effective to have the last line by itself, let it stand alone. That would make it even more powerful.

Anyways, thank you for sharing this. And I hope your situation gets better. One should never apologize for being "broken" for aren't we all broken a bit inside? We should never have to apologize for where we are at in life.

Take care.
