What have I done?

Here I am again, sitting on my bed, wondering about my life.
Everyday is a fight, a fight that I need to win, again and again.
I'm broke.
And if I'll ever be okay, the scars will still remain.
I know someday I need to let the past go, but right now I can't.
Too much is on my mind, too much is going on.
And everyday I'm wondering;
what have I done?
