My current T has never seemed out of sorts for our sessions. I usually have 6p sessions and am sometimes late because I have to wait for my husband to get home from work, so she has some time between to situate herself.

My previous T of 2yrs only had a couple times where she was really wound up. She told me her couple before me had a massive fight that made her anxious and she didn't get enough time to gather herself before our session. Completely understandable.
