Society just doesn't understand me.

It is so messed up that we can be so advanced in technology but society still can't accept people like me. I just don't understand what is wrong with people. So here I was trying to enjoy working on my schoolwork in silence when my asshole teacher comes to me and stees that im struggling on a problem, and he starts telling me "you're going to start paying me you need so much help." and he was laughing, then he started showing me how to solve the problem, when he was finished he laughed and said "I'll send you the bill." like what the fuck dude that stresses me out you know my family is poor because my obese brother spends all our money on candy, its not funny he used to be so skinny skinny bom bom skinny skinny but now his rolls drag on the floor. Why did my teacher have to bring up money in such hard times for me. This made me so mad I started crying and playing skin violin in my bathroom stall, once I finally could speak i went to the office and told them what happened. The old lady said we'll see what we can do, that made me so mad that this dumb old lady didn't know what needed to happen, I said: "are you a blind old lady anyone could see what you could do, you need to fire him for insulting my family!"
So basically I got detention for yelling in the office, but it's ok because I met an Emo girl in the detention room which is amazing because everyone went steampunk. She said her name was Shadovia holder of the shadow which is like the most epic name I have ever heard she is so lucky her parents let her change her name to that. I would change my name to Armagheddon Electrostrike Unleashed I would go by Arm for short. So basically I told her "LF GF"(looking for girlfriend) and she said ok so now my life is like 666X better now so I'm kind of glad that my teacher made me cry, but im still going to kill him in his sleep by cutting off his arms and legs and drowning him in his own blood. But I don't know how I can Introduce Shadovia to my family, I don't really care what they think but Shadovia might not like me if she sees my obese brother eating pixie sticks in our bunk bed.
when detention was over and I went home my mom yelled at me for getting detention again. I tried to explain that it was my brothers fault for being fat but she got more mad and sent me to my room and took away my alternative rock tape collection, without that I don't even want to live so I don't know what I'm going to do, Shadovia is the only thing I have to live for now. fuck society.
