Eating disorders are serious and need to be treated as such. There is help for you out there: meetings, counseling, etc. SOunds like you need counseling most because obviously you aren't eating because you are hungry, you are eating because you have emotional distress.
From your post it is obvious that you suffer from low self-esteem, you eat to "fill the hole in your soul" (as was said before), you gain weight, and thus the cycle is perpetuated.
I have a childhood friend who was anorexic in high school and was almost hospitalized due to it. From anorexia she progressed to cocaine addiction, beat that, then became a plastic surgery addict. As you can see, eating disorders can be a symptom of a much deeper problem.
Here is a ((HUG)) and hopes that you seek help.
