I've recently begun seeing a therapist for BED and I've found it extremely beneficial already.
I think it could be useful for anyone who is willing to be open and honest. Sometimes that is very hard in therapy. I have so much shame attached to my binge eating that it would be much easier to go in and say that everything is going fine. It's very uncomfortable to talk about this, but pushing past that has given me a lot of insight.
If you're still on the fence, take some time to think about what your goals are. Are you hoping to stop binge eating? Gain insight into what causes you to binge? Find different ways to manager your stress/emotions without binge eating? I think that having specific goals and knowing what you're looking for can help you figure out if therapy will be helpful.
Based on my personal experiences, I think you should give it a try.

Since starting therapy, I have become much more able to resist binge eating. My old method used to be white knuckling it and just trying to force myself to resist. Now I have so much more knowledge about what situations and emotions tempt me to binge and have a plan of what to do in those situations. And I have someone to talk about all of this with and keep me on track.
Whatever you decide, I hope you figure out something that helps! I am sorry that you haven't been doing well lately.
