Sleepless Nights 2

I really can't believe I of all people am about to say this but, I can't sleep!! At night I lay and my mind just races. Last night I tried putting myself to bed early and meditating to go to sleep but it still took me three hours to fall asleep. I then would wake up with my thoughts racing at least twice during a 5 hour sleeping period. I actually woke up this morning with my jaw hurting cause I was clenting them together all night. I never do that!! I am under more stress than I thought. I am exhausted and still feeling sick.... not good at all. I am just plain miserable and having to endure it alone because my family is gone and my, well people have other things to do other than keep me occupied.
