It's hard to take that kind of criticism from a loved one. My husband has started in on me lately to lose weight. There are nice ways to say it and there are mean ways to say it. What your mom is saying is just mean. I agree with the others - tell her that it hurts EVERY time! Remember, only you have to be happy with your body. If she doesn't like it, too bad!

Suggest she join a gym with you so you can both be healthy - not skinny, but healthy. It's harder to lose weight when you are depressed because it's hard to get motivated. On the flip side, once you get into a routine, you'll find that exercise actually helps with mood and depression. The hard part is getting started and sticking with it until if actually starts to feel good.
