Ok first that doesnt flow with the rest :
I dont know what to do
But my feelings for her are growing
It would help alot if I knew she loved me to
I even think of her in class so my grades are rapidly lowering

I would reccomenD:
I dont know what to do
but my feelings for her are growing
it would help if she loved me too
and in my grades it's showing

Ok next on that doesnt flow:

Well this poem ends with me still in love,
And wondering about her
But not to worry I will tell you what happens with us
Trust me I will write more

not sure exactly how to fix this one... umm. maybe...
The end of the poem, I'm still in love
still wondering of her
But no worries I'll tell what happens with us
Of that you can be sure

some reccomendations... dont have to follow them.. actually it's prolly btter if u didnt.. just kinda there to show yo some options.. meld it back into your style but make it flow a little and the poem would be perfect cuz the rest of it works really well.
