I once told my T that I was worried about becoming too dependent on her and she told me we could scale back sessions to every other week. She also told me, in another session, that she wants me to be careful about becoming dependent on her and if therapy takes the place of me reaching out to other people in my life, then we need to talk about it. I would say she is very aware that I could become dependent on her and that does not seem to be something that she wants (nor do I).
