You are definitely going through a difficult period right now. A couple thoughts come to mind. For the practical issues, how about an electric griddle, a crock pot and a toaster to keep in your room. A toaster is about 10 bucks. A griddle and crock pot can be purchased second hand since they can be easily cleaned. Goodwill stores and Salvation Army Stores usually have these items available. You could then get some hot meals with many more options. Do you have "marked" gluten-free condiments in the fridge? If your frozen items are packaged you don't have to worry about CC. If the outer package has crumbs on it from the freezer then rinse it under water before opening it. There are more things you can do, just give some specifics and we can brainstorm for you.
Now for the Family. I'm assuming you are living with your parents, brothers/sisters? I'm also assuming you are an adult? Ok, think about this. Call a family meeting. Let them get a good look at you and how your fairing. Tell them you are getting seriously sick again. Tell them how it effects you mentally and emotionally. Tell them how you feel they don't care about your well being. Tell them you need some support at this time in your life. Tell them everything bottled up inside. Cry, yell, rage, plead, whatever you are feeling. Ask them if THEY have any suggestions to help with CC.
Lastly, you can't give up. Seriously, it's not an option. If there was ever a time in your life to advocate for yourself, it's now. I know the feelings you are feeling. It's very hard, yes. You can get through this. If you don't have your health you have nothing, trust me on this. We can all help you with individual situations but your the one who has to do the work. We are all in this Celiac thing together!
