Feeling stucked

I know my situation is of my own doing, but I need to talk to somebody. I have been struggling a lot with my health and I’m very broke. I was in a long distance relationship during covid and after that he made clear he would not go where I was so I chose to go to him. And I love him, but I’m miserable. We ended up living in the basement of his parents (I know) and his mom is relentlessly awful. I’m pretty sure she’s a narcissist. I usually do what I’m told around her to “not trigger her” which has sucked for me but a while back I missed the queue on that I guess because I “misbehaved” in front of her. I’m in the process of getting an autism assessment, because I know I don’t behave naturally the “normal” way and other diagnoses have not helped. I know I’m struggling and it shows at times, but I feel so angry that I need to be punished for that. It’s exhausting being around her, because I was given this script on how to behave and I have to do it like a job. And this is not what I want with my life at this stage. I’ve told my boyfriend I want to leave and carry on with my life and figure out my *** with my family and in my home, and he’s so angry that I want to throw all our time together to waste just because I cannot play along with his mom. But this is constant stress. I don’t have a job anymore and every day I have less and less energy to pick up the pieces of my life. I have lost the thread of who I am, and I’m afraid I’ll stay lost forever. I know my own choices led me to this place, to these folk, I’m not trying to throw blame around. I just had to say this somewhere. If anyone reads this, thank you for your patience.
