AITAH for wanting to move out

Never made a post before so plz excuse the bad wording and spelling I have very bad Dyslexia

trying to figureout if im makeing the right choice i am a autistic adult(22F) with some other developmental issues with my brain.

❗warning there are sensitive topics like un aliveing❗

Im wanting to move out of my abusive home my mom is a hoarder and she verbally and emotionally abuses everyone and Sometimes physical primarily she threatens to off herself all the time if something dosnt go her way she Never lets me use my ssi (i haven't had new clothes sense high school other then birthday money) and Constantly saying im going to make everyone i live with homeless if i get a job or make any money at all. A friend recently gave me a offer to move in with her she only haves a 2 year lease but thats fine we will more then likely find a new place by then but i haven't talked to my Family about it yet as i know that my mom will threaten to off herself again or will try and withhold my stuff or i get disowned by my whole Family.

I dont want to lose my Family but the amount of abuse i have been thrue its destroying me and makeing me not want to be around anymore myself i have been told for years by friends that the things i have been thru are not normal at all. For example my older sibling with chase me around with a knife as a kid or made me run in a busy streat for something they droped or would ducktape/tie me up and lock me in a closet and even now Constantly saying how much i ruined there life and they still threaten to hurt me and sill chases me with a knife (sibling is almost 30 btw).

im wanting to get away from this abuse and this isn't even all of it but i need to branch off and learn to be a adult and to have a fresh start in a new safer environment for myself i want to get therapy and a services dog but i cant do that if im stuck here. My friends have yold me im not the ass hole but i need a person who doesnt know me to give me there thots

Plz let me know your thots and if im the ass.
