need some serious hugs please

I just got an email from my professor saying that my paper is unacceptable and I can either take a 'low C' or take an incomplete and rewrite it.

I practically killed myself just to get this paper DONE. And I can't remember the last time I got lower than a B on a paper... I'm pretty much a straight A student.

I'm so f-ing frustrated right now. I know it's just a paper and it's not a big deal, but this is just kind of the last straw in a whole big pile of hay for me. I'm so fed up that I'm honestly considering just saying 'f it' and taking the C. I seriously read the email and just started bawling. I'm still crying now.

I am definitely not taking summer classes, and if I get a good job, I think I might take a year off from school, because I really just can't do this anymore.
