I want

I seem to be empty,
and in some ways angry;
What did I do to you,
What was your issue;
I tried so hard to understand,
What I did to deserve your backhand;
I tried my hardest to make you happy,
even while I was bloody;
Nothing changed your temper,
while you backed me into a corner;
I'd scream, yell and beg,
while you laughed, spit and hit;
Now I find myself angry,
and looking for an I'm sorry
