Tech week and jitters

This week I had practice every day of the week. I started out all gung-ho, "I can totally have a sleepover, a party, and a four hour tech run today!". No longer. Now I am more " I can't even remember running that scene yesterday and I'm about to pass out."
Every day has gone until at least 8pm, later most of the time. And I'm super tired. My conversations are very intelligent. A tidbit from a couple days ago:
me: *coughs*
J- "what?"
me: "I didn't say anything."
J: "what?"
me: "what?"
J: "who?"
me:" how?"
J: "cat"
me: "Giraffe"
J: "How dare you say giraffe!"
me: "sorry!"

See what I mean? And in this week only I have said both adoikable instead of adorable and headbrush instead of hairbrush. This lead to a lot of singing " Where is my Headbrush!" backstage.
AND THE PLAY IS TODAY!!!! I'm sooo tired, I hope I make it!
