Sounds like a really good session, Rat (I hope it's okay to call you that - it is a compliment from me since I think rats are wonderful intelligent creatures!)...
My T made a similar disclosure to me when I first started seeing him and was worried about how he would judge my feelings about my previous T. And I felt like you - it was incredibly comforting to hear, although I am generally suspicious of that kind of personal self-disclosure.
Anyway, I don't think it's weird or that you're making a big deal of it. I can definitely relate.
Also... Yeah, I always count down too. There's this website called tickcounter.com where I create an hour-by-hour countdown... Except I haven't done it this week, 'cos I'm annoyed with T and hate him and never want to see him again etc.
