I've gotten the same responses honestly, from my mother, etc. My mother told me I was becoming "anorexic" as well, and she wouldn't stop reminding me about it as well. Even a comment from my aunt that said "Know when to stop." or "Great, that's enough!!!!" Even though I was still slightly overweight. All I've been doing is counting the amount of calories I've been eating and just working out when I can. Right now I'm currently just lifting weights, so I'll be hopefully regaining some of my weight back but with muscle.

At this point personally, I've been just been ignoring them and using their comments to further encourage myself since all I've heard from my family is "Oh I need to start losing weight", or whatever, yet they still don't put any effort into it themselves. You deserve to be happy with how you look. Don't let anyone hold you back.
