Goodness, that sounds like a rotten situation! I totally understand how dificult it can be to live with someone like that. My mother makes comments like "your too skinny" or "you look sick" even with just a loss of 5lbs. As for your parents buying trigger foods, what if you ask them to pick up some healthy snacks that are yummy like those Skinny Cow Candies or weight watchers ice creams, or even the 100 calorie packs. Have you tried having a heart to heart with your mom, maybe ask her to join you on this journey? If she decides to join you or not, dont beat yourself up about eating some the stuff she makes (small amounts are ok) just realize you made a bad choice, pick yourself up and make a plan to do better next time. I'm sorry that your mother doesnt seem to be supportive of your goals, if she cant be the support you need, look somewhere else (like Sparkpeople). You have to look past it and remind yourself of what is motivating you, whatever it may be. Not only do you owe it to yourself to live a better life, you owe it to your 8 year old!! Plus you have to show that ex of yours what he is missing out on!!!
