Depressed v. Depressed
You need them when you can no longer fake functioning. When you stop combing your child's hair, when you lie down 3 or 5 times a day but your eyes don't close, just like at night, and no matter how many times you get in bed or how long you stay in, you are alert, pained, exhausted, sapped, hopeless. I won't cover Chris Rose's or anyone else's territory. But you don't need anything until you can't get through the week without it or something. If you're still working, grading papers, cooking dinner, fucking, washing your hair and changing out of your pajamas, you're still on that side of the fence.
That said, most of the time, with the help (even if it isn't quite right and has to change a few times), you get better. Then there are those few of us who have more pus and treatments, most of which are painful. How that turns out, I'll let you know.
