I can remember a couple of times that my therapist's eyes welled up with tears. It was in response to my describing a situation where I was genuinely helpless and unable to protect myself from exploitation. Both times, I described the pain, but I was somewhat distant from it - like I was describing what happened to someone else. So I was not trying to elicit a reaction from her. But I'll never forget looking up at her and seeing the evidence that she felt my pain. It impacted me. For so long I felt shamed by my pain - like I didn't have a right to feel that pain - like it was my fault that I was in the situation to begin with. Seeing the tears in her eyes, and her calm presence of compassion was incredibly healing for me. I don't remember how she put it, but she said something along the lines of her wishing she could avenge my pain. It was so unbelievable how it felt to me to have someone hearing my story that clearly felt my pain and felt protective toward me. First time ever.

So.. I think it may depend on how it played out with respect to a therapist reaction. If they were crying buckets of tears, then I'd feel weird too. But the spontaneous thing where her eyes welled with tears was a very positive experience for me.
