Aggressive brother, urgently need

By the way, my brother is really aggressive and I think that comes from the game since it started there iwie (he is 11) I had 4 bruises and now I have a bump on my head. He snaps off quickly, for example, he does not want to go to school tomorrow because he has no buck, my mom said no and he is directly tricked and has insulted us. He also often insults my mother and I have already thought to bring him to a psychotherapist because his behavior is no longer possible, I urgently need advice, by saying brings nothing and if you say yes is quiet because he ausschmeickt also in the game or if you want to sleep he laughs too loud he says shut up

Then your mother should learn to be consistent

I would ban him first Fortnite. Or take the device away with what he plays. And yes, a little consistency could not hurt either. And maybe a behavioral psychologist

You should definitely talk to your parents and show them the bruises! Your brothers often believe that he can do what he wants, that's just not possible. My brother was also very rough, my parents have him then "taken to the chest". After that, rest was!

She is yes, she is strict and screams at him and wants to take away the ps4, then she does not do it and it goes on, she has taken what he has said, goes to my father and then we'll see

So she is not consistent

My parents know about the bruises and if they talk to him, it brings zero, then he blames us for everything

Then your parents should not talk but forgive punishment. Please take your mother away in the console.

And if she does not do it then should I do it or go to my dad?

Clear! And if the father does nothing, then verkabel the console, so he will think that the console is broken. And he will hopefully normaliesieren.
