Well I've been home with a depressed H myself and felt pretty much like you. At first I was just rather greatful to have him HERE (this during the bombings)...
And he did NOTHING...he slept, he watched old Star Trek re-runs...I DID cut him a lot of slack. Did it get aggravating after about month 2 or 3...a bit! I wondered if he "milked it" some.
But he DID start coming around. He's off his meds now and seems to be holding his own (no, he didn't tell me he was going off, but it's a good thing as Serzone has been recalled ).
