Im depressed and its school tomorrow...

I really don't feel like going, idk what to do.

I can't concentrate in school anymore. Im so tired, i feel so sad and empty. I try to work/do the homework and everything but its so hard when you can't think. On some lessons i just sit there & wonder what it feels like to be happy & being able to think and do things. I just wanna go somewhere and cry when i'm in school but i can't cuz then i'd look even worse. I have no motivation at all, i don't even make my bed anymore. I've been depressed for almost a year now...its getting worse and worse
