Honestly I must agree, I know the weight gain will set off your ED, but if you are prone to violence you NEED medication. If you become violent and get caught you will have larger problems than eating disorder. I am not one to say that everyone needs medication but for you if you cannot regain control of your thoughts through CBT you may need it as short term stabilization. It does not have to be forever, but I can see that you are going through a very rough period right now and you are in a very dangerous situation. I urge you to consider medication at least for a short time.
