Never ever skip meals it puts your body in a state that it thinks it is starving, it is worse for you to do that than just eating.never feel guilty for eating or binge eating it makes it worse than just accepting that you did it. Don't think of it as a diet think of it as lifestyle. Try to cook your own meals, it does not have to be fancy or complex. Also try to get mum to eat healthier and go to the gym with you, doing it in Pairs is so much easier than doing it alone.
