AITAH for acting cold to everyone in my family?

Ok so I'm a teen and my family is very unstable and unpredictable. Every day some unexpected member crashes out and the next day they act fine and that just doesn't sit right with me. Mostly my mom crashes out towards me as she overworks and has no social life/mentally unstable maybe. I just felt exhausted after every unexpected crash out from my mom or my aunt or my grandma or my dad. I can't rely on anyone here so I just gave up and am now cold to everyone. I don't speak much and even that is now a problem here. I'm just avoiding conflict as people love to argue and hit for no reason here. I feel kinda weird that I'm doing this but I just can't do it anymore. Being cold let's me not get startled when a person randomly crashes out here but I know they all do it because they all have some issues too. But I also feel fine doing this because it's not like I'm disrespecting or harming anyone like they did to me - just acting indifferent and distant. So yeah I would like some judgement and if you think that I'm the AH I would like some tips to help my situation.
