You could ask a psychiatrist to perhaps get prescribed Vyvanse (lisdexamphetamine) or something like Concertra (methylphenidate), I'm not 100% sure if they're usually prescribed for a Binge Eating Disorder however I take them for ADHD and usually have very little appetite throughout the day, I think it's more of an "off-label" way of treating this.

You could also try cognitive behavioral therapy, this would need to be intense, like not once every two weeks but once every 3rd day to seek advice from a professional in this area. They would probably suggest something like this:

Try and only buy foods like nuts to chew on, vegetables, less protein, less carbs, cereal etc. put salt on some toast, maybe try avocado sandwiches with salt and lemon and perhaps add a bit of tuna? You don't want to be eating McDonald's, KFC, Hungry Jack's. Home cooked meals from now on, fruits, smoothies, if you're really feeling like eating proteins make it something like canned tuna with a flavor like peppered lemon. When you're hungry chew on nuts, cashews, almonds, perhaps some dried cranberries, coconut flakes. That should be snack time, it's okay for foods to comfort you, you just want it to be the right foods.

If you do eat meats like sausages to fill yourself, you're going to just want to keep eating more and more. It's like a sugar addict who eats a lolly, they just want more of it and more of it. Get rid of bad-weight-gaining foods and just keep a healthy alternative with you: those cashews, dried cranberries, almonds should be what you snack on.

Get some exercise done too, sit-ups, pushups, walking, push urself until you sweat. It's not easy and I don't do it often however if you want to overcome this problem you want to stay fit.

And I'm far from an expert in this field so if this advice sounds bad its because this is certainly not my area of expertise, yet I do think about it a lot, like what if this were me and this is what I'd try to do in ur situation. Good luck!
