I don’t want to “get help” or “cut back”

So my mother thinks I am a alcoholic and I do admit I enjoy booze more than other things in my shitty life. she keeps trying to get me to cut back and steal my drinks from me then gets mad when I steal them back and hide them from her. We live in the same house because there is no way I can afford rent in my country and I am autistic and can’t really work enough hours without being burnt out to afford rent. Thing is she likes to bring up drinking by emailing my mental health professionals and it annoys me I stopped going to therapy for a while dispite servere problems because my mental health professionals wouldn’t stop bringing it up even when I told them to drop the subjects. I eventually went back to a different women and told her to not mention it at all. My mothers pestering won’t stop and my sister has joined in at first I knew It was out of concern and ignored it but now it just annoys me and makes me irritable drunk or sober. I started drinking in secret purely because there nagging. It’s my life and I’m usally happy when I drink but they keep pushing by getting on my nerves about it when I’m drunk wich is the only time I am happy.

I no longer care if they are being “concerned” or not it is ruining my happiness and taking away what little joy I have in life. Idk how to get parents to piss off when it comes to drinking habits and I don’t care what there reasons are. I have been depressed for 14 years and I’m nearly 22 now. So finding something that takes the problems away when no amount of therapy,life changes and meds work is not something I am willing to give up on.
