Although you won't fully know until a doctor diagnoses you, it appears that you have a severe food guilty anxiety, specifically with binge eating.Have you ever logged your intake? Not to count calories, or fats or carbs, but use it to track when you're eating, what you're feeling before eating (hunger, boredom, depression, anxiety, anger, stress) what you've eaten, and how you felt afterwards (guilt, sad, full, too full, anxious, etc.) From there, see if you can do some self evaluation.Why do you think you do this activity with food? Why do you think it makes you feel the way it does. Is it body image? Is it stress related, childhood related, relationship with your parents or someone close to you?
If the activity doesn't change, I would recommend seeing a doctor to discuss it further. They can recommend you to a therapist, and to a nutritionist.Remember, food is life. Life is good. Take a deep breath and try to logically focus on the behavior rather than panicking about it and feeling unnecessary shame.
