School is tough in general.... I remember I once moved to a new school and made no friends. I once went into the bathroom to fill my instant noodle bowl with water before I microwaved it in the cafeteria and someone called me some pretty dreadful names and told me I was only welcome to eat my lunch in the bathroom. Wouldn't let me out. My grades suffered because I was so stressed, and my parent's thought it would get better for me, I was just adjusting. It was infuriating. I once got grounded because my teacher called them and said I wasn't participating in group activities, but I wasn't participating because my group told me to shut up and sit away from them because they wouldn't work on the damn assignment and I was trying to get them to do something. I lose group marks because I don't want to get in trouble because my group won't work, so I do everything. And they profit from it!
I hate school.... Good luck though!
