I feel like i was just reading something I wrote about myself. You described almost everything I was/am going through however I also have a bad disassociation problem, thats one of the things were working on in therapy as it usually happens while driving. Although I do have some trauma in my history. You might as well (not suggesting you do but don't know, just saying you never mentioned anything). I've also gone to my family physician and did blood tests

I Started seeing a therapist after one particular bad night in Sept. I ordered a large pizza and wings, the pizza was doughy because it wasn't cooked long enough and the wings were gross and fatty. And i still ate all of it, after feeling like crap, both physically and mentally because of how much I just ate, I googled some therapist and set up a few appointments. Now i've been seeing one, once a week since Sept.

I would suggest trying out a therapist. even just going to the consult, as most provide a free 30 mins just as a test drive. Seeing what they say and figuring out if they can help.
