What do I do here?

So I’ve struggled with depression for years. When I was really bad, I lost my appetite completely and would eat once every 2 or 3 days. Needless to say, my stomach shrunk quite a bit, and since then I’ve been battling with my weight. I guess I kind of trained my body not to eat, and so now it’s a real effort.

I got down to 97 pounds, and as I’m 5’6”, it almost landed me in the hospital. My doctor ended up putting me on an appetite stimulant, which is worst case scenario and I’ve only been able to manage to gain a measly 7 pounds, and it’s been since June. I don’t have an eating disorder, but I guess my mom has PTSD from thinking I was dying for a long time. I get asked about 3 times a day if I’m taking my medicine right, if I’ve eaten, hey Amberly weigh yourself in front of me. I’m 19 years old and being told daily that I can’t take care of myself. What do I do??
