I was pretty depressed for a long time. I had no energy and I couldn't sleep very well. In the end, it seemed helpful to just take a bunch of time off, unplug from everything and sleep. I more or less forced myself to exercise most days and that helped too. But I did learn that spirituality isn't able to provide happiness on demand. Rather, the big freeing disappointment seems to be that I just become more and more compatible with unpleasant thoughts and feelings.
