Other people, even therapists, are not robots. She was going to miss you. That's life; you wouldn't "comfort" a boss if you quit for a better job with more money would you and they were going to miss you. I think you should find another therapist, maybe a male one, and discuss this issue, right away. It is "you" to obsess about this therapist in this way; you're doing it, it's not being done to you; you have some issue with leaving females or females leaving you or something. The other person can't "make" us feel anything; our feelings come 100% from our own experiences and perceptions. She may have had something in her eye, for all you know, that made her look like she was going to cry?
