Hi, heatherguay, and welcome to Psych Central! We're not experts on eating disorders, but some people here do have them. I think the issues are are you staying healthy, getting the vitamins you need, and maintaining a proper weight, and also why you are not eating.
Some people do get too busy to eat at times. And I don't like to cook either. How about stocking up on some healthy foods that are easy to fix, even microwave meals along with fruit, etc.? Then you'll be on the safe side and not worry your relatives.
