Aw, sorry you're having a tough time, Montana. Is exercise an option? That's the best cabin-fever buster I know of.
I had a few nights in a row of waking up and being kept awake by anxieties. (A lot going on, hubby's in the midst of job search, etc.) That's unusual for me, did some zooming around the house (wanted to go to the gym but sozlet's sick and can't leave her in the childcare area), that helped. Just, like, going up and down the stairs more than necessary, playing chase with sozlet (your son may be too old for that now

), that kind of thing.
