You ABSOLUTELY have the right to terminate however it feels right for you.

It sounds like the bigger issue is the fact that you feel like your therapy has never been just about you. Have you talked to T about that?

And it's REALLY hard to talk about...but super important, because that's how I learn to work through things in my relationships outside of T.
