Sometimes I wish I could run
To where I'll never be
I want to scream I want to shout
And no one notice me
-- I think in the last line you should add the word 'have' after the and. I think it'd make a little more sense and it'd flow better. :]

The flow was pretty good overall, I think that's a really important part. You have to make the words roll off the reader's tongue. The rhyming was pretty good, and it's a very relatable poem. I liked it. :]

Keep writing.
