I understand. So the way I lost weight . . . don't recommend it but I did lose 70 pounds. Probably the best thing I've done . . . besides therapy and talking to the people closest to me is going to CURVES. I love that place, I love the people I met there. You and your daughter could go together and a lot of times they have like a buy one get one free kind of deal especially at this time of year. Not a huge fan of TOPS but every group is going to be different. I went with my mom when I was about 15, 16 and it wasn't a great experience for me but thats another story.
Take care of yourself. You can do this.
