This poem is critical for me.

[¿Que Pasa?]

I have to get this poem right because I suck at poetry... Please give me useful feedback.

I feel ashamed and abolished for what I did to you.
Why can’t you let me fix this, it’s something I can do.
But I can’t fix things if you wont let me in.
I still feel as if this little fight, is one big sin.
I said it before, but I’ll say it once more.
You are everything I love and adore.

No, this can never happen again.
It was more than you could handle.
I feel lifeless without my sweet freshman.
And I also feel downright awful.

I need to have one more chance.
I need to have one last shot.
I know you’re still sitting on the fence.
I know I can fill that last slot.

I can still make everything better.
I can’t make anything worse.
Instead of a poem, maybe I’ll write you a letter.
Or I can do a play, but I’ll need to rehearse.

I want one thing and one thing only.
It’s the thing that doesn’t make me feel puny.
This one thing is you.
This time, I’ll be true.

It's not bad.  There are a few parts I might recommend rewording somehow with a similar meaning.  For instance:

¿Que Pasa? wrote:

And I also feel downright awful.

The last line doesn't seem very poetic to me, just adding it on like that.  If it could be combined into the same phrase, somehow, without 'and I also feel'), I could recommend that.  Not that it's bad how it is; really, it depends on how you read it (but if you're not going to be reading it aloud, then I think a re-wording is in order).  The first line is fine, I think.

Also, here it seems that it taking 'It's' out of the second line might be good (plus the period on the second line to a colon or some such to accomodate).
