Crying

Why is it that I am crying inside
And why does my heart feel like it is stopping.
I wonder at times what should I do,what road should I take.
I feel like everything is wrong with me and never right.It seem at times that no matter how hard I try everything seems to fall. Why I ask myself ,but they is no answer to this question right. No matter how hard I try to be happy I always end up sad. Am I going to be like this forever? Why can't I be happy? just for once.
