I've known my T for more than 2.5 years and I'm back in therapy since the start of this year. I still struggle to talk to her. I find it hard to bring up topics. My T has been very patient and understandable. She asks me questions, she brings up topics we've discused before, she understands me very good, she understands that it's hard for me and she also knows how my mind works/thinks. This makes it a little bit easier to say things.
I have said once that I'm afraid she finds me annoying because I talk so little. But she said that's just who I am and that I'll never be a big talker and that that's ok.

I think she handled it very good from the beginning. With previous T's I had things to tell and I wanted to talk about things, but I was so anxious to tell them. They didn't really know how to handle this/me, even though the website of all those practises also mentioned that they treat social anxiety. But they never could make me to really talk and they never asked the right questions. And some of them kind of gave up on trying ot get me to talk.
