not good enough

i'm not a good enought student.
i'm not a good enough daughter.
i'm not a good enough friend.
i'm not a good enough christian.
i'm not a good enough helper.
i'm not a good enough listener.
i'm not a good enough person.

i'm tired of not being good enough. if i'm such a waste of human space, why did god put me on this earth? i really want to leave. give my parents a chance to have another child...one that can make them proud. because they've made it very clear that i'll never be able to do that. i just really wish i didn't have to be alive...
