This is beautiful! Although the theme is vague I can see what you're trying to express. The use of first-person narrative is very effective as it's made the poem more personal and intimate. It's like being rejected for so many times that you reject yourself eventually.

The rhyme works as well. Well done!

I like the irony here... and the last line... it's so true... I also love the stanza about the emotions not becoming their opposites, but really just disappearing.. that's definitely something I can relate to and it was well done

PS If your bored check out the Review Game and its Review Marathon (links in my profile)

'And I can't lay the blame by you,'-- this line rings funny. Maybe 'can't lay the blame TO you'? That doesn't sound much better, though.
'Everyone else who had a chance,
Because if you can, then they can -'-- These lines sound forced, not as smooth as the rest of this piece.
This piece has a feeling I think everyone has related or will relate to. Nice word choices.

I know exactly the feelings you describe here. Someone close to me has a habit of not showing any excitement at positive things I tell him, and that usually robs me of the joy I had felt initially about successes etc. Makes me not want to tell him or anybody about the good things that have happened any more, because I'm afraid such a reaction could spoil the good thing for me. You have expressed this much better than me in your poem. I especially like the one-line-stanzas that structure the poem and often give a contrast to the preceding lines. You express that feeling of disappointment really well.

I really like this!

I love the format and the fluity of it all.

Very nice! :]
