I never have checked on my T appointment before hand, but for a long time I was paranoid every week that I had the wrong day/wrong time or maybe she would forget/double book? I was SO nervous before every appointment until she came out and got me. It has been 2.5 years, and she has not once double-booked or didn't show up, so I have gotten comfortable with knowing she'll be there.

Though, she once was 15 minutes late and I was FREAKING out thinking I was at the wrong date or time or misheard her (we had switched times). Turned out she was just running late. Thats only happened once, though.

So I understand how you feel.
