When did you first know you had a problem with Binge Eating Disorder?

I have been overweight almost my entire life, but I feel like my binge eating disorder really started few years back. Now I have very hard time controlling my eating and I've started to feel more depressed and hopeless because of it. I have struggled with binge eating for years.

Since 4 months when I let self-harm and smoke. My anxiety focus after that only in the food because it's simple and easy way for reduce it (or create the ilusion of reduce it)
