This was a very good poem that expressed a lot of ideas and feelings... the rhyming was a smidge rough though... like in this part" I thought I have a lot of things
A family, so many friends
Happiness you think it brings
But no one understands..."
i think that you were trying to make this rhyme but it didnt excactly flow... and in this line "But it's not enough"
try making it's it is not... it might make your poem flow just a small bit more... but that is only my honest opinion... over all nice job though....
