Dont go out anymore since I started losing hair

I saw a picture of myself on my birthday last year with huge gaps in my hair. The same night my mom made fun of me and pointed out my hair loss. I think I cried all night and Ive stopped going out at all this whole year. I used to have so much confidence even with my hair loss, but ever since then I have huge anxiety about being photographed and I’ve also gained weight. I want to get my confidence back but i dont know what to do :(
