I'm also sorry you're dealing with this. Disruption like that can be difficult. And it's OK to be upset about it, even if it can't be helped.

When my former marriage counselor's wife passed away, he also saw us just a few days later (I didn't realize at the time she'd passed away--found out about a week later). But then he ended up canceling our next session and taking a week off after the funeral. He had teenaged kids at the time, so I imagine part of it was being there for them. For me, it shined a light on the reality of the therapeutic relationship--I wished I could give him support, but that was for his family and friends to do, not clients.

My ex-T told me, in relation to that, how she'd had a loss (I think maybe her sister?) at one point and thought she was fine to come back and work with clients right away. But she said she felt like she was thinking through soup (like her brain was full of soup), so she ended up taking some time after that. I wonder if that's what happened with your T in part, that she thought she was good but realized she needed a bit more time?
