Most of the things I talk about with my T now were not relevant during our first meeting. It was an intake for help with my insomnia/sleep issues. It's now evolved into so much more. I'd rather stuff it all back in as I've recently revealed much more than I ever intended to.
I do have to say that I'm heading down the same road as you. Wondering just how much I reveal to the intake team at the new clinic if I do decide to go. Hard to trust a new team with such sensitive information. I know a little of how you're feeling right now.
