I'm starting hating school so bad, I don't know why it started that feeling I used to like going school before but now everything seems so bad to me, I don't like my classes, I hate doing homework, months ago I could do that without problem, now everything has changed..
Get some sleep, people get the feeling every once in a while, i know i did, get sleep and exercise
I had the same problem, started hating it and then i started uni went to uni for 2 years and failed my classes, so now i just went on a trip for 9 months working overseas and traveling.
Now i feel like starting school again, so i'm gonna move back and go to uni again.
Try taking a year or half a year break.
