My T told me he has learned a lot about what clients go through from me, because I've been so honest. I believe that meant both about my feelings (like feeling clingy during positive transference and irrationally angry during negative transference) and about things I confessed to (internet snooping on him). I think I could be open partly because I knew from this forum that my feelings and actions were not unheard of -- and sometimes extremely common. I knew other people here were brave enough to bring up topics with their T's and it helped me bring things up with him, things like weird dreams or embarrassing daydreams, I told him about all of it. My T learned through me but he also has the forum to thank, in a way.
