Sorry about your grades, I know how you feel....I just got a 70 on a quiz, but, let the slip in grades motivated you. You aren't a stupid person, you know the work, you are just having a bad time right now. Instead of thinking about all the bad stuff, think about where doing good in school will get you,, what you will be able to do...and that it is GOOD for YOU... and you deserve to have good things!!!

Hang in there,,, i'm rooting for you
