Not body confident

So New Years day I went out to eat with my husbands family. His mom asked what our resolutions were this years. We hadn't really made any ( I wanted to be a bit healthier but didnt tell her that). She them told us both that we ahould make our resolutions about losing weight. I was shocked! I did not know how to respond so I just shrugged it off but honestly, it really bothers me. I know I have gained weight this year. I got married a lite over a year ago, I started birth control, I had a miscarriage. All perfectly fine reasons for gaining 10 lbs in year! I am not proud of it ans I'm workong on it but I was very hurt and very upset that she would tell my husband, her son, that he also needs to lose weight to his face! He is a perfectly fine weight! I dont know what makes me angrier!! It made my confidence in my body go down as well my attitude for her. Idk what I should do or if I so anything at all.

Sorry for the long post, needed to let off some steam!
