When my own depression gets bad (worse than it normally is anyway) I just want to be left alone. (Actually I mostly want to be left alone anyway.) It's actually a fairly serious bone of contention, so to speak, between my spouse & I because she can't stand to leave me alone during those times. I suppose she's afraid of what I might do to myself... which probably isn't an irrational thought on her part given my history.
I've also gradually pulled away from PC somewhat over time. Some time ago I closed my public message board on my profile page. Then more recently I locked out my private messaging system. And, most recently, after losing our beloved Schnoodle to a combination of kidney disease & old age, I stopped frequenting the Games forum here on PC. I just don't seem to have any enthusiasm for it now. I am making myself keep up with some of the posts in the other forums though. I just make myself do it. That's my only strategy. I just make myself do what I need to do.
Best wishes...
