I'm impressed you didn't have a meltdown and start crying, I'm sure I would have!
Thats awful though that they can't help you. Have you been to a sleep clinic? If the regular exercise didn't help you sleep, try swimming! I also have sleep problems, I take Ambien which really helps but I know the nights I go to my water aerobics class, I do sleep better!
