i'm so done with my mom. i'm only 15 and don't know what to do.

I'm a 15 year old trans guy. My mom keeps blaming how i feel right now on hormones and just "being a teenager" (not taking hormones/T), But ive been feeling so shitty for months. Ever since i came out in 6th grade, my mom had been "supportive" of me, but she really hasn't. She outed me to my dad about a year ago, keeps saying if a divorce ever happens it's my fault, etc. She only uses my chosen name when i'm really upset and i'm not around my dad, which pisses me off. She wont talk to my dad about my identity either, and ive never even seen him show his veiws on the community (based on what he watches though, im assuming he hates me). My mom still talks to me like a baby, how she does to the damn cat. I have time limits and restrictions on all my devices, shes so paranoid about me looking at porn for some reason even though i dont in the first place (ew). She told me she has the right to lie to me (no wonder i have extreme trust isssues). Told me straight to my face twice if a divorce between my father and her ever happens, it's my fault because i'm trans. Wont accept the fact i could possibly be autistic (both brothers are diagnosed and i show the EXACT signs as they show) because i'm supposed to be the perfect child with no problems. Yells at me when i give her advice on how to do something properly. Makes fun of my comfort items. Never listens to me when i try to talk about my interests. This has been happening and just worsening over my entire childhood. I feel robbed of being a kid. And i think from all this ignoring me and brushing me off my entire childhood is causing me to age regress. I act like a toddler, cuddle with my comfort items, i even use a pacifer that's hidden in my drawer. I feel like an absolute shit show and need help and advice. Sorry about it being rushed and possible spelling mistakes.
