The best advice we acn give is to get as much rest as you can. Have you tried all the formal and informal networks (SSAFA etc, friends, social services) to get your youngster taken care of during the day so you can quite literally put your feet up?
Once you are at your level of attack frequency you have to be in bed as much as possible. I expect your are at your wit's end already, but there's little more we can suggest until you have had plenty of rest.
I'd hope that the "forces family" could work well for you - don't accpt a no!
All the best
