Emotional Eating

It's so easy to fall into a trap of overeating and emotional eating. I believe most of my overeating comes from emotional eating. I just eat to fill some void, to feel something, to feel important. The feeling of full is like being drunk for me. I love to drink because I feel empowered by my drinking. I feel nothing can stop me. I'm invincible. And stupid for thinking so. Why do I need such crutches? But, most importantly, how do I get rid of these crutches? Any advice?
