Yes, she's a psychiatrist.

Not THAT much, but I prefer using person's name when I address them. It's just how I talk.

She's very strict about her boundaries. Calling her by her first name would be too informal for her, and she can't have that because she (as a therapist) can not be my friend. She's there just to help me to understand things about myself. And she wants me to respect her boundaries the way she respects mine. And I can understand that (on some level), it's just this Dr.-Mr. thing feels so wrong to me. I'm not used to this.
