I'm 21 and I'm OBESE, severely actually. I have 3 children (no mistakes to me but down to either no contraception or failed) i exercise quite a lot I do at least 4-5 or more miles walking a day. I do eat healthy but I snack. I have tried diets, exercise.. Nothing seems to be shifting it. I an getting really depressed.. I cry, I can't even look in the mirror. I want to loose weight without sag!!! I need help!!! What can I do? I'm come to the end of my tether.. I am contemplating surgery tbh. Help me please
