It's still early (3 months), but I haven't found my therapist to get irritated about anything, including my self-doubt (and worse). She just sort of takes it in, asks questions, and the intensity dissolves at some point. Not sure how that is happening.

I could not deal with a therapist that gets irritated with me. I've had that with previous therapists who put their egos into it, and it feels distancing and blaming.
