@typhlosion I try to keep around high protein things and little carbs like crackers or chips always around! Try to keep something you like. The best things to keep are small things you can snack on because it sometimes turns on the "oh I need food!" bit of the brain.
But when things are really bad consider keeping around those meal replacement shake things or bottled smoothie. They're better than nothing, and I find that if I can't physically eat I can still drink things!
I agree with others that weed helps but I don't know if it's a legal option for you
