Too Tired to Sleep

I dragged my ass out of bed at a little after 6 Friday morning. I ran around all day and worked all evening. It was probably nearly 1230 am Saturday when I got home. I can't sleep. Even though I'm tired- nay, exhausted- I can't sleep. I hate having my schedule all whacked out. I suppose it'll get better. After all, I only have 2 more days before vacation and then, wonder of wonders, I am changing shifts in October. I hope I like it, half as much as I like my current shift.
I do need a change but all I can think of is losing my friends. I hate that.
Fortunately, I make new friends, at least superficially, on the surface. God knows I don't want to inflict the reality of my life on anyone else!
