Alright, good concept and good emotion in this piece. I can tell you mean it, and that's what usually makes a poem a good one. Now, the one suggestion that I would offer is your rhyme scheme. Try and keep it consistent. It seems to go ABAB CCDE DDFDA... I would suggest something along the lines of, ABCB DEFE... etc. Or ABAB CDCD... etc. If you have a hard time with rhyme scheme, there is always the world of freeverse. :) Just my suggestion.

I did like these lines in particular.

There's always someone better than me
Who perfects all the things I can't do
There's always someone better than me
But if you try to take him, then you're screwed

They have a lot of feeling, and really do begin the poem off nicely. It shows where this piece is most likely going to go, and they also work nicely together. Best wishes and blessed be. *Athame
