Elizabeth,
I have a similar experience as you and Dexter. After one of my hospital stays I almost stopped sleeping completely for almost three weeks. I think I averaged about an hour or two a night during that time. I have to admit that it was the worst time of my entire life. I literally thought that I was going crazy again and was going to have to be put away forever.
Please do not let it get that bad for you. Going to the doctor is wonderful first step. Sleep is so important whether we like to realize it or not.

I wanna hold you high, you steal my pain away
There’s so much left to learn, and no one left to fight
I wanna hold you high and steal your pain</font color=blue>
