Desperate for advice?

Survive. Just survive. School isn't life. School is a game you are forced to play, but there can be good prizes at the end. Everything will change for you over a relatively very short period. Survive as best you can. Get some sunlight, as much as you can. The brain can't sleep or function without sunlight. People don't understand this. And it is actually true, what doesn't kill you, makes you stronger. Concentrate on surviving. Otherwise, they win. Do you want them to win ?
