Now that was a grade-A post, at once grandiloquent and eloquent whilst being useful and helpful.
"My therapist said depression can best be dealt with therapy, a little medication, and daily exercise with the focus on daily exercise."
Spot. On.
"So why don't you go running for an hour, come back to your house, and know that this is your house. And that you have been able to survive this long."
Always frown on these specifics for of what do WE know, the OP? --Maybe RUNNING AN HOUR is raucously impractical. However, any exercise, and I like to focus on walking, for however long, on a daily basis... and you've got a winner.
Oh but James dude. The rest - "you are capable of behaving differently from how you feel. It will be uncomfortable, it will seem like you're putting on a charade, but that's just the depression talking. You aren't responsible for how you feel, but you are in control of how you behave."
Well that is powerful insight.
