I don't know what the closing eyes and sighing is about. I would say ask about it if you have the guts. For me there have been times I know my therapist is distracted, he's looking at his phone more, or just scattered seeming himself that day. I've never called him out on it. I've felt like he was bored, but never when I was disclosing something heavy... more when I was just rambling on. Perhaps your scatteredness that day made her feel like whatever it was wasn't too important. Could be she had her own issues going on as well... you really never can tell with people.

One day in particular I felt like my therapist was really struggling with something emotional himself, like maybe someone he knew had died... later I asked him about it and he just said something vague about maybe something horrible did happen that day. Sometimes I feel like I can read more off of him than I get by listening to him. More and more I think I can see through the fantasy of what I wanted our relationship to be, to what it really is... and that is a guy trying to do a job, acting supportive and caring whether he feels it in the moment or not, and trying to connect with me.
