So tired today!!!!

I often say you don't want to see me on less than 6.5 hours of sleep. Well lastnight I got less than 6. I went to a friends house lastnight, we made dinner and hung out. I didn't get to bed till midnight. Then I had to be up at 5:45 to get my car to the mechanic at 7. I feel like I am breaking down. I am a complete sleep-a-holic. Not only am I super tired, but my body is revolting against me. I have a headache and my stomach hurts. I am jittery, this could be from the lack or sleep or from the 2 LARGE coffee's I had to try wake myself up. I don't know how I am going to make it to 5pm when I can leave work and take a nap.
