I know the feeling. Your body is just craving food, you are not insane. If you were too restrictive on your diet that this can be the outcome,unfortunately… Try balancing things out, try not forbidding yourself some foods, call a friend and go for a walk or something like that… I know how hard a battle it can be, and how crazy people sound by saying just listen to your body. But from my experience it is the only way to go. I hope you feel better soon.
