I know I'm experiencing things that didn't happen in my relationship with my parents. Really basic fundamental things, like being allowed to screw up and not be rejected, and having the experience of mattering, it mattering if I'm upset, etc.

I think there is an element of reparenting in T relationships when they work well, because the gaze, attention and devotion of the T is something you may have missed in childhood and those wounds will open up whether or not you are focusing on them in the room. But a T is not a parent and the relationship cannot function like a parent-child one - what it can do is fulfil SOME of those functions in a new way.
