Character Voice

(Character with anxiety)
I have to get a good night sleep tonight. I have a big day ahead of me. Everything is going to be so much fun! I can't wait! ...
What if my friends don't show up... or my dress doesn't fit?...
WHAT IF I GET SICK?!?! Oh no! Am I getting sick?
Is it hot in here?
What if he changes his mind about me? What if he doesn't want to go with me?
What if he has already told me and I just wasn't listening or he forgets to pick me up all together?!?
Why is it so cold in here?!?
I need to calm down. ...
Since when is it 12:54? Im going to be exhausted tomorrow.
Great.
