school, unfortunately

I hate school. SO much. why is everyone so insufferable. My physics teacher recently quit all of a sudden?? what the fuck. i miss her. I'm in year 12 so my classes matter a lot. My maths teacher sucks. he's so horrible that another teacher took personal action within the school to get him removed. we are WEEKS behind. I'm getting a new maths and physics teacher next week and I don't know anything about him but if he sucks I'm genuinely going to give up. I'm failing music. There's so much work in art. I'm too tired to focus in school. I have someone with a weird obsession with me and it's really creepy. My friends are beginning to annoy me for no reason. It's only the first week of term 2. why. I'm going to fail year 12. I'm going to get a bad ATAR and not get into uni. I'm going to be doomed to a life of retail for the rest of my life. why is the education system like this. why does my school suck so much. why is my principal horrible. why can't i just have stable classes like everyone else in good schools. there is one other person in my physics class. we don't know what we're doing. kms.
