Welcome! I spent about a decade in depression. I am, thankfully, doing very well now on Wellbutrin and can't even imagine having depression that was resistant to treatment.
Before I figured out that was a I had was depression, I used to get some relief and additional energy from acupuncture. And as far as the eating stuff - I used to find (and still do) that doing something I'd be completely absorbed in would take my mind off the food - basket weaving, knitting, sewing. Something that took so much brain power there was nothing left to want to make more toast with butter.
Good luck to you!
It's about commitment, not motivation.
