If you're not comfortable with her, you said that you'd be transferred to another T soon, is there an option for that to either be a bit sooner or to not have therapy until then, I think you said it's September when you'll get the new one?

To me it sounds that even if she now somehow stopped her behavior and didn't say anything about masks and so on at all, it'd be on your mind. That's understandable, but probably not what you actually want to work on? If it were me, I'd not want to see a T who makes me (maybe unintentionally) think about other things than what I'm there for all the time.

The session length thing, maybe that's a good point to discuss with a new T right at the start, i.e. "how long are our sessions". I've heard from a lot of people who are scheduled by the hour but only have 50 minutes sessions.
