From my experiences with my t, and like ten plus years of end of session hugs, i would say the main reason your t was "uncomfortable" was because she was not in control of the hug. My t ALWAYS let me know that HE was the boss of the hug. Period. So i really dont think your t is saying anything personal about you or herself. She is just saying, use your words. That applies to good feelings as well as a child's tantrum. And in therapy, its probably a short thread connecting the two, as you explain.
