Healthy Weight?

Hi everyone! I have never been happy with my physical appearance and struggle horribly with self confidence and body image. I don’t like to talk about it too much... anyways I need advice. So I am currently recovering from an eating disorder which “caused” me to get down to 102 from the 130 I was senior year of high school. It’s been a long process and I’m really struggling with binge eating during recover. any tips? what is a good weight for a 5’5 20 year old female? I gain weight in my face and stomach which are two of the most noticeable places I feel... Any tips on gaining muscle also? thanks so much..please no hate i’m being genuine and really need the support.😌

p.s. the picture attached was me at 106..i look “happy” but i was basically starving myself on a severely restrictive vegan diet. I put it here just as an idea of my frame....
