My dad died and my brother is a whole different person

It’s just so bad I don’t know what to do. He talks crazy, saying scary stuff because I can tell he’s struggling

He gets angry and has outbursts. Tonight, he yelled at my mom and I saying that we are against him but we aren’t!! He says these things that make no sense and then takes it out on us.

I’ve been doing my best to deal with it but I’m only a 20 year old and I’m in school too, I have finals coming up and I just know I’m going to fail because everyone is arguing.

Everytime I sleep, I can hear him yelling at my mom downstairs too, and it’s just so stressful. When it comes to my end of the work, I’ve been doing A LOT.

I clean, shovel snow, make food, commute from school and back, take care of the cars and bills, work two jobs while all being a full time university student. I don’t know what to do please help. I don’t know what to do anymore and it’s already hard enough on me then I gotta deal with this crap everyday.
