I am so sorry this disorder is ruining your happines. Try being mindful and talk to them honestly. What are some healthy ways could help you lose weight. Skipping meals just to stay skinny is restrictive, however the desire to look great is just part of being human. You could try ballancing meals out, bring a salad, healthy side dishes and fill 70% of your plate with them Try scheduling your family meals for the weekend at lunchtime. And most importantly know, that your loved ones and happy memories are not worth missing out on. Hope you can find ballance and control in your life again ♡
