My (16 almost 17F) parents divorced when I was 6 and both of my parents moved in with their parents(it's quite normal here). My dad(42) has custody of me but I mostly stay with my mom(39), we share a space that would very well be suited for one person. We have a bunk bed and the room is definitely not enough for 2 people esp a teenage girl with her mom. I have no privacy and my mom is under the idea that she's "friends" with me and always plays the victim in every situation.

My grandma is straight up narcissistic and also has victim syndrome (the apple doesn't fall far from the tree). I am basically their caretaker now bc both of them are too lazy to do anything. Any happy moment I have is ruined by screams 24/7, I want some peace after literally coming home at 8.30 pm from school but my mom is always on the phone and SO loud.

Just one example to show their behavior, we were visiting my great-grandma and great-grandma(my grandma's parents) in a rural part of the city and my uncle and aunt also joined us(mom's brother and his wife). Things were also so bad there that my uncle had to talk to my mom about treating me like an actual human being instead of an object to take out their frustration. He also said I had gone quiet and no one was noticing, he even offered me to stay with them for one semester. I really wanted to but I go to school with a school mini-bus and their place is too far away from my school. They've now gone NC with both my mom and my grandma(happy for them tbh).

There are too many things like this and I might look like I'm exaggerating but I simply don't know how to explain all the stuff.

Anyway, onto the actual problem. Next year I'll take the university exam and (hopefully) go to university. A few days ago I was talking to a friend on vc while playing video games. I was talking really slowly but just as I was saying "idk what I'll do but I don't think I'll speak to them after I'm gone" my mom entered the room. After then it was absolutely chaos, anything from "who do you think you are??" to "how could you abandon your mom???". Honestly I was just so sick of it at that point I just packed my bags and went to my other uncles house(dads side). I generally don't have a good relationship with my dad either since all he does is talk about my flaws and how I'll never become anything in life. His brother and his wife actually like me and tell me I'm welcome at their house anytime I want. (one way they make me feel loved is when you enter their house there is a HORRIBLE painting I did when I was 8 hung on their wall) so yeah I keep getting texts from everyone saying I should come back and stop being a b*. idk what I'll do I missed like 2 days of school and its not exactly good for me bc we have an important event coming up. So AITA?? What should I do??
