From what you said I can't guess what from the content of your conversation could have made your therapist feel unconfortable. Then again, it might have been something different, like gestures, a look, anything really. It's probably the therapist's countertransference. I'm sorry you got to hear that comment - if I were you, I imagine it might shake my trust in my therapist's availability for me. Whatever your concern is about this, it might be a good idea to ask your therapist directly if you want to find out. Anyway, the therapisat's reaction is the therapist's reaction and not your fault. Therapists are trained to deal with varioua types of discomfort and it's part of the job, so you don't need to worry; and if you do, perhaps seeing what exactly it is that you're worried about could shed some liht on your emotions and thinking process.
