Well, I must say, I recognise the sentiment. Whilst the poem itself rhymes and flows (moreso than my own, by all accounts, it appears) I would point out two things:

1) The repetition of "you can't make friends" in the second last stanza, line 2, and the last stanza, line 1.

The next is, of course, even more of a mere suggestion than the above:

2) Perhaps you could tell people what went wrong, and use this as the main focus of the poem instead of the sheer hate.

Of course, that's what I'd do, and that's why we're two different people with two different styles.
But keep in mind, this style of "I hate you" is very common here.

Oh wow, what a poem! Very strongly written. Great job!
