ever feel that way?

I am exhausted! I feel like I could fall asleep in the middle of traffic. I feel like I am fighting something, but cant figure it out. Tested my pee, and it is normal. no fever. I am stumbly, crampy, and grouchy. I feel wrung out, but have no explaination for it.

Anyone else ever do this? does it lead to something, or is it just something that will be gone when I wake up?

im off to bed and its only 6!
