Log off the computer for the evening and try to relax. Take a nice warm bath to relax you and then sit down and read a book with the girls. It will help keep your mind off stuff.
I also had the problem with sleeping. Once in awhile I have to take an excederin pm to help me sleep. I also turn the clock to face the wall so I can't look at it. It helps!! I have started sleeping a little better. Some nights I have a hard time falling asleep but once I am asleep without the clock in my face I can stay asleep.
Please get up in the morning and make some phone calls. You need to do something to get your life on track.
