AITA for finally exploding on my mom and extended family after years of chaos, mess, and hypocrisy at home?

My mom has problems. My family has problems. Growing up, I watched everything, moods, tone shifts, lies, backstabbing. Think Shawn from *Psych*, but toned down. By 8 I could read people. I knew when to ask, when to stay quiet, when to disappear. It made me good with people, but it also means I know exactly where to hit if I want to hurt someone. I’m planning on therapy. I’m the middle of three. My mom is a single parent, and I know she tries, but our house has always been chaotic. I knew extended‑family drama by nine. I used to be a nice guy Now the streets killed me. In 7th grade things got physical. Police were called. And let’s say some WWE stunts. Teachers always called me a good example. I don’t vape, drink, or get in trouble. By freshman year I joined activities just to stay out of the house. I made a rule: if it isn’t mine, I don’t care. I clean my room, do my laundry separately, manage my own things. The rest of the house is overwhelming. We eat at my grandma’s because our kitchen is basically unusable. I go to a competitive prep school. I had a 3.4 weighted; now I have a 4.2. I’m trusted with leadership roles and even keys to supervise events. But at home I’m “irresponsible.” I need eight more driving hours before my permit expires. My mom keeps delaying and won’t let me use my own job money. She says I can’t be trusted. So I started pushing back: “Are you sure I’m responsible?” Petty, yes, but I’m trusted everywhere else. Junior year has been worse. More fights. Police calls. Getting kicked out temporarily. Today was bad. Failed a test and a quiz. Sick. Played horribly at open gym one of the few things that brings me joy. We started losing and I became the scapegoat. I left halfway through, close to crying. Sometimes a man just wants comfort from his mom. Instead, I got a cold shoulder. She still took me to my grandma’s. I barely ate (I ate earlier but also to give a show since I was already at my peaked from that could shoulder). Everyone got offended. My grandma said I’d become a failure and “family doesn’t treat family like that.” Something snapped. I brought receipts. Every backstabbing moment I’ve watched for years. Every fake smile. Every betrayal. I said I’m tired of chaos and hypocrisy. I called out aunts, uncles, my mother, grandparents. I said I lost respect when my mom told me she wished she never had me. I called her a bitch. She said she wants me out and mentioned emancipation. I said fine. Since she want to be bringing it up every time, go right ahead. When I left, she was already pulling papers (she files documents for others, so she knows how). I doubt this was just going to “blow over.” like every other time. I cut this and left out many things especially background.

I know I exploded. I know I burned bridges. But after years of this AITA.
