Hertsukfem31, I'm another with depression. My post-surgery plan was to make sure I walked around my neighborhood every day. Sometime I could only manage 10 minute, but some days it was a lot more. But I got up and moved. That will physically help some of the depressive symptoms (not the disease itself).
Then anytime I craved chewing, I'd eat sugar-free Jello or a sugar free Popsicle, both of which were suggested by my Very Strict surgeon. They even gave me Popsicles in the hospital! They sated my chewing craving.
Lastly, I created a support team. I asked friends to come visit me, I spoke openly with my boss and co-workers, I have a email blog to let my friends know how I'm doing, and when I'm not doing well at all. Some will send me joke, or funny YouTube videos, or come by to visit. One friend, who is a sommalier, came up with the idea of having a Water tasting night. I'd stay hydrated while discussing the differences between all the brands of bottled water. It makes me smile just to think about it.
None of this had made the recovery any easier, or my fight with the desire to eat any simpler, but they have been successful at keeping the worst parts of my depression at bay.
Don't give up! Keep trying new things, and remember to move and stay hydrated! YOU CAN DO THIS! I BELIEVE IN YOU!
