I'm getting about 4 hours of sleep a night. I'm exhausted but I CANT SLEEP! I'm exhausted and wide awake until midnight when I finally pass out. then I have super vivid dreams or nightmares, wake up at 4 am still tired but unable to go back to sleep and just lay in bed waiting for my 5:30 alarm for work. then I work a 10 hour day come home, be mom and wife and repeat it all over. on my days off I nap around noon for a few hours but night goes the same. anyone else just exhausted?
