(I'm assuming that your bulimia originally started, as most people's seems to do, because of a diet or some sort of food restriction.)
Have you read/heard of the book 'Brain Over Binge'? The author has a very different approach to 'bulimia recovery' and I think it might be worth giving a read if 'traditional methods' haven't really been working for you (assuming you've tried to attempt to recover via them already). The book is more of a biography-type thing but there's also a workbook (separate to the book) which may be helpful.
I actually disagree with the above poster's point 1. Dedicating your life to ED recovery isn't really the point of ED recovery and I think it makes it harder to really 'recover'. The people that I know who I consider to have truly 'recovered' from their ED just don't care about all the stuff typically associated with 'ED recovery' - eating fear/trigger foods, body positivity, following instagram recovery blogs, etc. They just live their lives like everyone else who has never had an ED which I think is the most helpful thing you can try to do.
Eat as though you didn't have an eating disorder - eat as though you're feeding a friend or family member rather than yourself. Read up about intuitive eating (if you haven't already but you probably have) and get a regular eating pattern in place, at least until you think you have a decent grip on your body's hunger signals. That should sort out any binges that happen because you're not nourishing yourself properly.
When you feel the urge to binge for non-hunger reasons, try to distract yourself with something, anything, else. Again, it might help to imagine if you're someone in your family or one of your friends. Or, if you can, imagine yourself before or after your ED and just do things that the before or after you would want to do instead of a binge. Any hobbies? Books/movies/TV programmes on your to read/watch list? Languages you think might be cool or useful to start learning? Sports/exercise (preferably ones where you can't work out or see the calories you're supposedly burning)? Is your room in need of a bit of sorting out/tidying?
It might take some practice and effort and you might slip up once in a while but the important thing is to try and move on and hopefully the binge urges will go away eventually. And with no binges, I don't think you'll feel the need to purge...?
