Food addiction

I struggle with overeating. It's definitely tied to my stress level. It's been worse lately than it's ever been.

I'll go to the store and buy a massive pile of junk food. Soda, chips, ramen, cookies, crackers, popcorn, candy, ice cream, etc. I describe it like what a 12 year old would buy if he found a hundred dollars. But when I actually get it home, I'll eat and eat it until I feel sick, then eat some more. And at that point it doesn't even feel good to eat it, but I keep going nonetheless. I'll also overorder fast food and eat it over multiple days. Like buying multiple pizzas or a ton of wings at once. Even if I can manage to not keep snacks, I'll still get really hungry and eat multiple dinners or snack on fiber bars or whatever else is around.

There's this mindset that I have to eat it all to get rid of it as fast as I can so I can "start over and be healthy again", but then I just end up going out and buying more. I have bad teeth already, and this doesn't help. Often I don't get good sleep because I've eaten so much that my whole body hurts. I want to lose weight and live a long life, but I keep falling in the same trap over and over.

Not sure what to do.
