Really interesting question Learning1
I find this hard to answer in a way because when I hear the words 'authority figure' I usually think of someone who is cross, who shouts at someone, who exerts their control over the other person (so i see it in a negative way) and my therapist doesn't do those things.
However I do see her as someone who I look up to, like a mother figure (im female, so is she) who has more wisdom or something. And some people would say this is an authority figure as parents usually are.
I guess I do because i dont view us as equals exactly, she has more power than I have naturally and I usually feel like a child in therapy..but not in a bad way.
