Excellently written poem, with a lot of greatly expressed emotions in it. You did absolutely superb job with rhymes, the flow of this poem is perfect!
My favorite lines are:
-Since you didn't want me on your friendship's train
Then why have you put my soul on a chain?
And why have you sealed my heart and brain?
I know no happiness I only know the pain-
Love your poem but the last line...shouldn't it be like this:
Can't you see how hard it will be for me now to be happy again?
Well, see for yourself it's a beautiful poem anyway!
5/5 from your sis lol
