Is there a diagnosis for this ?

So I’ve never been insecure about my body growing up mainly because I never really noticed, I got in a really bad situation with this guy who raped, emotionally and mentally abused me he constantly mentioned my weight I have always been naturally thin both of my parents are skinny my mom picked up a little weight after having kids she a size 3 not as skinny but still slim, I found myself trying to force myself to eat more because he would constantly compare me to other women to me showing me pictures and saying things like “how you black and skinny” “real black women have curves” “you’d look better thicker” so on and so on. so after getting out of that I still have this body issue where I’m over eating to the point of getting sick I’ve bought so many weight gainer products and nothing works it actually seems like the more I eat the more my weight decreases which is weird, I’ve stressed myself out to the point where I’m 85lbs and I’m 23 standing at 5’2 is there a condition for this ? I expressed my concerns with my doctor but she just brushes it off saying things like “so many women want to look like you just embrace it” I really hate looking in the mirror I avoid going out as much as possible in fear of people staring at me and whenever my weight gets brought up I get triggered to the point where I isolate myself and my anxiety kicks in.
