22F drinks 10 beers on avg. a day

hi guys, i’m a 22yr old female who drinks on average 10-12 beers a day. i still live with my mother, but when i’m not here on the weekends and i’m at my gfs house i tend to over drink. i’m autistic, have tourette’s, ocd, adhd, and depression. the only thing that seems to help other than being with my girlfriend is beer. i tend to stick with the light beers, as i don’t want to gain that much wait with the remedy i have right now. i know it’s not a remedy but it seems to be the second only thing that reduces my stress and anxiety. i’m completely in love with my gf and we have absolutely no issues, no fights, no anything. been together for 2 years. so no it is NOT her. i’ve been traumatized before, SA’d by a 17 year old guy at 11 years old, SA’d by a 16 year old girl at 19, and same thing with another girl at 20. my mind is fucked up tbh, and all of that trauma has caused me to want to drown it out. in y’all’s opinion, what should i do?
