Just a thought....is there any way you could start part-time and work your way to full-time? Maybe only 2-3 days a week? You could give a legitimate excuse without giving away your MH issues....that it takes a while for you to get used to the routine. Just a thought. If you start a little more gradually instead of full-time right off the bat, maybe it would be easier. Or you could look for something that is part-time with the possibility of going full-time in the future.
