Since you already know the cause of your overeating, it will be quite easy for you to deal with it. The next thing is to work on how you take your food;
Increase your intake of liquids, water, buttermilk, juices.
Practice yoga, then take eating as meditation, feel, smell, relish every atom of it. Practice eating so meticulously that it doesn’t seem a task that you can indulge in, any moment. Even after swallowing do not stop feeling the path of your food (as far as you can). If you’re too busy to do the Yoga thing, you can fill the hole with something else. I don’t mean a literal hole, I mean the metaphorical one that you’re escaping from dealing with by filling up your senses in unhelpful, unhealthy ways. Aside from finding someone to talk to about this to try to get to the root, which I think is a good idea, try other activities. Read a book, go for a walk, do a puzzle. Anything to put off the unwanted food for 5, 15, 30 minutes. Anything you do that isn’t unnecessary eating is a success. Then if you eat don’t beat yourself up. That only adds stress and gives you another pain to eat out of existence. You are not bad. Food is not bad. You just need to redefine your relationship with food.
