I feel really sick and depressed ?

I've got school tomorrow and im not really doing well, plus im looking at colleges soon and its making me so fricking stressed. I don't even know what i want to do anymore. People say "do what you love" But the matter is, i dont actually LOVE anything. I've got nothing to look forward too, sorry, but i dont actually give a toss about christmas. Times going too fast and NOTHINGS going well. It's just too depressing. Help me out? I need a General cheer up. :/
