Aita for fighting my little brother

This whole thing started off when my little brother got into a fight with my little sister and my mom started yelling my name to stop it which is all she does and so I came done and slammed him and kicked him when he was on the floor sounds it extreme but 100% deserved to understand this better he is a guy who just talks trash and I just can’t do anything I held off on him for a while now he legit talks about me being fat when he is obese he is 5’5 180 pounds and I am 5’11.75 and weigh 184 or around there he legit talks trash about my mom before and she babies him to a extreme and more but back to the fight afterwards he talks about fight me and how he didn’t cry spoilers I later made him but the thing is all he did was shell up and my mom and older brother were holding me back and I accidentally hit my mom the thing is my mom loves to victimize herself and I just realized this after the fight and when it was done my mom started calling me a animal and crazy and a idiot even though this was mainly her fault but ye she than said she was going to make a report and call the cops and report me to them and more lore is that when I would do something about my little brother she would think we were playing and I would hit him and my mom would call me a idiot who doesn’t know how to play and throughout the whole thing my older brother was the only one that was sane which is very surprising but explaining more of this is more trouble than it’s worth but also my little brother pees the bed and leaves his poss clothes behind the door and the sheets on the basement steps so my mom could clean it and throughout this whole thing I reliazed my whole family thinks I am crazy even I just stay on my stuff and I am the type to hold my anger in there’s more context but it’s more trouble than it’s worth
