Hi and welcome to Psych Central. I am sorry that your question didn't get answered sooner - hope you are still reading.

The main difference between bulimia and overeating is that bulimia involves purging in some way. People can be bulimic and be any weight - from severely underweight to normal to overweight. Overeaters don't necessarily purge. They might not even binge - they might just eat more than is healthy on a regular basis, a little here and there.

It sounds like you have a lot going on. There probably is some connection between your eating disorder symptoms and your other symptoms. One disorder may be a way to cope with the symptoms of another, and they could all have common roots. Are you in treatment for any of the things you mentioned? Please tell your therapist about all of the things you mentioned here, as they are all important and all relevant, and should all be addressed. Most likely it will require addressing your anxiety and mood in order to see improvements in the rest of your symptoms including binging and purging. We do everything for a reason, and even though it isn't necessarily a good way to deal with our problems, it does serve a purpose for us somehow.

TC,
