I sure have ... I call it the Nervous Diet. I've lost many a pound on it. I remember baking a potato and trying my hardest to choke it down while my fat cat was meowing for food. I just ate what I could. The problem is your body goes into anorexic mode and holds onto everything it can, so once you can eat again (and you will, believe me) you stand a chance of gaining more weight than where you started. So just be careful when you start eating normally again not to overdo it. Don't listed to well-wishers who push cookies and high-fat foods on you trying to "fatten you up" cuz it'll do just that. If you get too low on energy to do high intensity workouts, just do what you can and eat what you can. Don't make yourself stress even more about eating when your body is just reacting in it's own way to a stressor. Doing whatever exercise you can will help with the endorphins but mainly time will help. I'm sorry you're going through a hard time, it stinks I know. A high-calorie protein drink will probably be very good for you, just try to stay away from high sugar, that will not help your mood and only give you temporary energy. Good luck & take care of yourself.
