How to stop binge eating/eating too much?

I am an extreme binge eater.

Whenever I start eating, I just can't seem to stop.

Does anyone have any advice, is there any medication I can take (I am legitimately diagnosed with Binge Eating Disorder, I'm not just looking for an "easy way out pill")

Let me clarify a bit, what I'm talking about is not as much a "I eat when I'm bored, and to solve this, I should just distract myself until cravings go away or etc."

I've already been able to control myself from eating mindlessly/when not necessary.

HOWEVER, I still have to eat. And my problem is, when I start, it's really hard to stop.

Even when I'm full, I still want to eat more. Yes, I recognize I am full, but for some reason I still want to eat. There have been several times where I am actually painfully full from binging, but yet I still want more food!

Once I finally pull myself away from food I am fine.

Honestly, I'm even afraid to have snacks because I know once I eat that snack I'll want more.

Right now I'm kind of sticking to the minimum number of meals a day to prevent eating too much.

I really don't know what to do. Does anyone have any advice to stop themselves from binging too much? Or have any recommendations on medicine or anything else?

Thank you.

-And just a note, I'm actually pretty healthy for the most part. I exercise a lot, and most of the time I eat very healthy. However, my parents who I live with are extremely UNHEALTHY, and whenever I'm on a binge, I'll reach for their unhealthy foods. That's when the problem begins...
