Hello Nimportequoi: The Skeezyks doesn't know what he has since he's never received a diagnosis. But he is almost completely solitary. And depression would certainly be one of the elements of any diagnosis he might be given. So we probably have some things in common.
I can't say that I have any of the specific coping mechanisms you describe. However, music is certainly a big part of how I manage myself day-to-day. I listen to a lot of chant... mostly Buddhist & Hindu. And it tends to lull me into something of a trance-like state. Often, as is the case as I write this, I'm listening to chant videos on YouTube. I spend a lot of time here on PC & most of the time I'm listening to chant videos. It puts me into something of an altered state where I think my time here on PC almost becomes sort of a meditation, in-&-of itself.
