I think I am over boundaried, myself. I don't let people in - not that I really understand even HOW to do so in the first place.....I go really numb and kind of shut down if it feels too close. My T seems to want me to call him or reach out more but it is a struggle.

I know Ts are affected by their clients. Many of them care very much but they have to keep it professional or it wouldn't end up being therapeutic, IMO. It just depends on what the client needs to define how the boundaries should be set, I think.
