For me, it is about trusting that he is a professional who wants to do a good job. I find that easy enough to trust, with my T. If he is professional he won't ever violate my confidentiality or judge me or drop me as a client unless he absolutely has to. And he has never made any empty promises, which would kill the trust, I think.

For me, therapy is not about becoming more trusting in other people. I need to trust my T, but I need to not trust people outside T's office - and so there is no element of using what I learn about trusting T in my outside life. That might also be significant.
