<human>: Let me preface this by saying that we're 3 kids, and all 3 of us have ADHD, so things can get hectic at times. My( 15M) oldest brother is a pretty chill guy, no problems with him.

The last 2 years i've ben to a boarding school, so i haven't had a lot of family issues. I moved home about 1.5 months ago, and my little brother is practically driving me insane.

He's always yelling, swearing, never cleaning up after himself(including not flushing the toilet that us 3 kids share). My mom keeps trying to keep him under control, but he just doesnt give a shit, and i see how much it's stressing her. My father isn't as sympathetic as my mom, and he will be much more strict to my little brother. Eventually he'll do what he's told, while calling my dad names. 

Now, my room is right next to my little brothers. He'll start his PlayStation whenever he damn pleases, with super loud volume. He'll also be making random "beatboxing" at 7 am, when the rest of the house is trying to sleep. If i ask him to be a bit more quiet, he'll simply make a farting noice at me.

Today i was out for 1 hour, handing out job applikations. I didn't bring my Keys, because my brother was at home, but when i got home the doors were locked. I tried ringing the doorbell, but my brother ignored me. For 20 minutes, in pouring rain.

I finally call my mother, she calls my brother, and he opens up the door with a shit eating grin.

I dont know what to do. He has no respect for anyone(he's also cyberbullying kids on his PlayStation, but whatever). My mother is stressed out, trying to control him, and my dad is getting more and more frustrated. I don't know what to so, but i want to keep some sort of family peace. 

We have tried family counseling. Guess who actually brought his Nintendo, and said absolutely nothing.

Could you distill the essence of the text into 1-3 sentences?
<bot>: My brother is a disrespectful little shit, and he's ruining our family dynamics. Do i wait until i can move out (3 years) or do i try to work on it ?
