Sorry to hear you're having such a hard time at the moment hon. Ok what about if you bulk cook? Make a large amount of something and portion it up so that you dont have to think about cooking for the family everyday? Or do you have a slow cooker? Then you could put the food on in the morning and let it cook all day and you will have something wholesome ready. Get the family to help out when they can too, dont allow them to leave everything for you to do, give them chores to do that will help you out.
