I need help - severely disabled brother makes it HELL for me to study

He has severe autism. I'm not even using this as a joke. I am dead serious.

He has meltdowns for at least 4 hours daily - where he just screams and cries at the top of his voice. He has ruined my family's life.

I used to be such a great student - I got nearly all A* for my gcses. Back then, he was younger so his behaviors weren't as severe.

But I messed up my AS because of him. How the fuck can you study with a human siren present in your house 24/7. Not only this, he's also physically attacked me multiple times. I have to keep him in my room for many hours daily to give my mother a break.

His behaviors have been more severe now that he's gotten older. I am so scared for the future. Everyday I ask God what I did to deserve this.

Is anyone else in the same boat as me? I don't want to feel alone in this nightmare.
