I had a similar issue with my mom. She is very overweight and has been all of my life and we were also eating buddies. She just couldn't imagine how I would live without overeating and made every negative comment possible. She was suppose to go with me to mx when I had surgery and the she backed out. I stayed strong about the decision to have surgery and went alone and have no regrets. I don't think my mom is jealous, she is so addicted to food and it's so much a part of her life that she can't imagine living without it and is not willing to face the fact that the diets are not going to work, she has to change her relationship with food in a drastic way.I think my mom projects her own fears on to me because she's not ready to make changes, but I AM! She has been a lot better since surgery, in fact she makes comments about how I appear to be more at peace with life, she is very proud of me but can't bring herself to the point of looking at her own problem, I pray she will one day, she's very important to me and I worry about her health all the time.
