No need to apologize -- You've actually explained it quite clearly, which is no small feat with gov't programs(!) That supported work program sounds like a good one. I hope you're able to get into that at some point. (Meh. Don't worry about that guy.) Do they have it set up so that one can work not only in a job suited to them, but also to a number of hours that is appropriate to how they are doing? That'd be pretty sweet.
Is giving a month's notice usual there? Here it's usually 2 weeks, at least for the kinds of jobs I know. Either way, it's always nice to be able to see that point, to reel it in from that "forever" feeling. Makes it easier with a countdown.
(Good Morning! That's a nice tnetennba! Sorry, wherever the word "countdown", is, I can't help but think of Moss…

)
It sounds like you've got a good game plan with good reasoning behind it. Let us know how it goes, ok?
