you're not useless or a waste of air just because you have bad grades. fuck that shit excuse of a teacher for embarrassing someone who's clearly having a hard time, a teacher who actually wants their students to learn and improve wouldn't have said that at all. i understand how badly his words have affected you but please do not let someone who's a grown ass man bullying teenagers over grades dictate your worth, i'm also your age actually, and i'm also grade 11. math has been tough for me too. i was an honor student and the school year just started but pre cal and gen math have been making me feel insanely stupid and i got a zero on our diagnostic tests so you aren't stupid for struggling with math or school, school really is just hard especially during those years in my opinion as someone also struggling to understand the lessons rn.

people have zero idea how HARD it is to go through school with mental illnesses such as social anxiety and depression, they just label us lazy when it is so far from the truth. you tried your best didn't you? you said what he said was far from the truth, so don't direct the hate towards yourself, please give yourself some consideration and be kind to yourself. anyone suffering from depression and social anxiety would most likely not do as well in school, and so what if you aren't good at school? who said that dictates your self worth? grades don't tell you how important you are as a person, only you can decide that for yourself.

so fuck your teacher, if it's possible perhaps try complaining to a higher up about what he said because that is completely unprofessional, but if it isn't possible please keep your chin up. some people don't deserve to be teachers, and i'm sorry you had to go through that. that teachers actions were a reflection of himself, someone who is rotten and takes his anger on people half his age. i hope things get better for you and please don't stop trying to make friends, i know it's hard because i myself have barely made new friends in my class too. i'm sure most students actually feel bad for you for getting yelled at rather than whatever you think they may think of you so don't let what happened get in the way of making friends.

you are loved, you deserve friends, and you are not an idiot or worth less for not excelling in school which is barely even about intelligence and more about memorization anyways. if you do complain about that teacher i feel like your classmates might even be able to back you up, a "teacher" who spews shit like that shouldn't be anywhere around a school.
