I feel kinda the same as growlycat. My change has happened slowly. At first, I only did new things to please my T and Pdoc. Over time, I actually found that I was continuing to do it on my own.
Some of the things that T has done is simply getting me used to a topic. Example: going outside. First my T had me just think about it. Then I was to simply sit on the sidewalk. Then I had to walk around my neighborhood. I then started going out more with family and realized that was all me and not my T's suggestion. Now I'm trying to get myself used to the idea of a class or volunteer job. I also am currently working on dentists, health, and being comfortable with the idea of driving again.
What could my T do more to help? Hmm... She could get me used to being comfortable in new situations by walking with me around the building or outside (it's terrifying to me to see someone somewhere where I don't normally see them). Sometimes I wish she would push me more on difficult topics. Personally, I wish I had a little more reassurance from her. But I am still in the beginning stages of therapy...again. So I have a ton to work on. Even T joked that we won't have a shortage of topics for a loooong time
