Are you concerned that she's annoyed or concerned that she will terminate because of being annoyed? Because I see the first as pretty commonplace with any two people over time.

If it's the second concern, then it would be worth asking your therapist under what circumstances she has terminated therapy in the past (if she has at all). Mine recently told me of the two times in over 20 years that she terminated someone, and both examples were extreme and far from anything that would happen with me.

I do think it's possible to annoy someone just by asking them over and over if you are being annoying, but with a therapist the thing is to ask if there is a level of annoyance that leads to termination. I doubt she will say yes. If she does, that would be a good thing. Who needs a therapist who can't handle someone else's emotions and insecurities?
