I'm starting to panic. No email.

Options and thoughts:
1. I can call her.
2. I can wait, since my appointment isn't until tonight.
3. I can email again.
4. I can assume she's back, seeing other clients, and has no time to email me yet.
5. Maybe she didn't get my email.
6. Maybe she's sleeping.
For some reason I don't want to call or email yet.

I guess I'll wait. If she didn't get back, she would have had to call, even from Europe. Right? I didn't hear of any plane crashes.
I'm breathing slowly. I wish I didn't care so much.
