Exactly... truly depressed people cannot function on even the most basic levels.
WAS's seem to function just fine when they are sleeping with somebody else and being wined and dined or when they are prancing around town without a care in the world. Suddenly though their "depression" is "overwhelming" when they have to play grown up and behave as a grown up.
If *something* new sparks an interest they are not depressed, they are bored (usually with themselves and are too lazy to do anything about it so they find somebody who will).
My H used to tell me all the time "this is so hard!". Which part did he find hard exactly? Sleeping with his young "friend", golfing at expensive courses 3 times a week, going on 16 vacations partying like a frat boy? It's funny when you ask these fools what they find so hard about all of THAT they have no answer.
It's amazing how clear you become a year or two later. I sometimes wonder how on EARTH I could have been so stupid!
