I think I have an eating disorder.

I just realized today when claude pointed out very humbly that I might have an eating disorder.
So for context, I am unable to lose weight. Every year I just end up gaining extra 5 kg. Now before anyone says that I should go to gym, I workout 5 times a week. Like strength training, weight lifting (i literally do chest press with 22kg dumbbells) so yeah its not that I am not moving my body.
But its my relationship with food. I eat alot. I eat even when I am full just to finish the food. I eat when I am stressed. I eat every time I walk out of gym feeling exhausted and its not healthy meals. They are burger fries coke and every random fried food you can think of. And although I look big (for a woman, people words) I cannot do anything about it. Until I address this deep issue of my disorder.
