Hey Scott,
I can tell you from personal experience, that depression does impact physical health. Perhaps you will recall, but a few months before you left the site, my Mom's finance passed away. Though not quite as bad as losing someone as close as your situation, I can tell you I experienced a range of effects, all of which were made worse by the fact that our income was shortly thereafter cut off, we had no vehicle and then just before Christmas 2014, we got evicted. Fortunately, I found work just two months prior and we found a place to move to.
On its own it is terrible, but when taken with a whole bunch of stressful problems and so forth the impact is undoubtedly magnified. Seeking medical attention was a a good move, something I was never able to do many of the times I needed it, especially all of the times I needed it mentally.
(I had actually planned on making a subtle exit after my term in fantasyland was ended, but unexpected circumstances led to me f**king off a bit earlier than planned).
We got it back, a full year later. And in four days we lose it again.
