Writer's block sucks. I hope that you get around it !
The subject at hand is "I'm always hurting you, but you still stay by my side." It has always been a weird concept, trying to understand why people stay with an abusive (physically or mentally) mate. Maybe they are afraid, or they actually care that much. Human are intriguing creatures, with very complex thought processes (there I go again, sounding like a scientist *sigh*)
1.) The second line of the sixth stanza has an extra "out."
The bolded words tell the meaning of this poem with simplistic clarity. I actually think that you should add that line somewhere in the piece. With that line, might I recommend adding a more happy (for lack of a better word) line? It might ruin the piece, but it could make it a better melodramatic piece.
