Honestly, I think getting some kind of boundaries on how available the T is good for clients (and Ts too- prevents burnout). It's all about us, clients, learning how to cope on our own, not how to be totally dependent on others only to be crushed when it's eventually taken away. Yes, some level of dependency is great and vital to learn too- this is what I'm struggling with, so I know.
Having said that I think your feelings are understandable- even though she is still much more there for you that many T would be- and really if I were in your position, I'd probably feel the same. I do believe talking with your T about that would be great.
