I'm sure that your T knows that these secrets took a lot of courage for you to express, & sharing them was a big breakthrough in your deciding that you could trust him/her.

if i were you, i would definitely talk about how you feel embarrassed after sharing this information. (of course this is up to you) i think bringing it right up front that it felt embarrassing is probably going to ENSURE your T knows how much emotional attachment you have to the things you've shared.
