How to deal with triggers? (TW)

I have been rather sick as of late with something the doctors can’t figure out (but isn’t contagious) and one of the main symptoms is loss of appetite. I suffered with a combination of Anorexia and Bulimia on and off for the past two years and had just re-entered recovery about 3 weeks before this all happened and about two months from today. I’m a relatively normal weight and extremely active, strong, and overall healthy most of the time. I play multiple sports and do weight lifting, jogging, and hiking as a pastime (not as an extension of my eating disorder). My muscle mass makes me appear larger than some other girls and my family, specifically my dad and sister have poked fun at my weight my entire life. Even though I’m one of the healthiest people in my family now, they still compare diets and disordered eating habits in front of me, urging me to try them or acting shocked at how much food I served myself even if it’s a normal portion. I’ve come to terms with this, but what’s been bugging me has to do with my recent illness. I was talking with my father about how difficult it is to be starving without a que for what you want to eat and a visceral disgust to food (this is purely physical and even foods that I love or would binge on are unappealing now). It was making recovery and staying healthy very difficult as my sports season starts and I’m getting more exercise which is causing me to drop weight far faster than I ever would when I wasn’t restricting. He responded that he had been having trouble with his new diet too and cutting calories can be hard sometimes. I clarified that it wasn’t a diet and was disruptive to which he responded that maybe my body was responding to finally getting exercise and going outside by lowering hunger cues (it started before my sport). He then finished by saying I should follow them. I expressed concern about passing out on the field if I did that and he said I might want to eat a piece of bread before games just in case. He was suggesting I eat nothing except a piece of bread and then exercise for 3+ hours. He said that I have stores of fat for a reason and my body knows what it’s doing. He then said that we could go to the doctor if I got too skinny. He basically said it was okay because I’m fat. I don’t know how but he seems like he hates the way I look more than I could hate myself. I don’t know what to do. I’m miserable and I don’t know how to be sick and in recovery at the same time. They seem more mutually exclusive every day…most of all, I don’t know how to deal with the constant body shaming or get them to stop talking about diet around me. I can’t get away and they’ve ignored me when I brought it up before because they said they will talk about whatever they want and how I take it is my problem. Any advice?
