My husband is the same. We have nearly split up so many times over it. It is hard to know what is the illness and what is pure fuckwittery.
From reading a bit about the subject I have gathered thus:
Agreeing to plans then cancelling them at the last minute
Difficulty getting out of bed/spending extensive amounts of time in bed or separate from loved ones
Sleeping A LOT.
Worrying over silly things.
Having impossible expectations then getting upset when they are not met.
Having anger issues (he is currently NC with his brother, who has similar issues).
Getting obsessed by tasks. I only have to mention I have lost something and he turns out home over to find it (then forces me to clear up).
General anxiety over DD's welfare, my welfare, anxiety over our whereabouts, anxiety over money, everything. Asking the same question over and over again.
My DH tried medication but all the different types made him sleep even more, and he was seeing weird stuff, not conducive to an early-riser postal worker. He was discharged from therapy when his boss refused him time to attend (he offered to do split shifts).
Can I say that when there is anger I don't stand for it. I tell him to wind his neck in, and go and calm down. He used to use physical violence, now he walks away.
I think he has had it all the time I have known him, but he was only diagnosed about three years ago.
The mess is normal. You have to force him to see it. He cannot see he's made a mess because all he can think about is his other problems. Don't clear it up, tell him he has to do it. And he has to look after the children. There is looking after him, then there is allowing the behaviour to stick around.
