I don't think I've ever had a T say they were concerned, but in my experience outside in the social world, some people use "I am worried about you" as a mechanism of control or manipulation, as in whatever they say they are worried about is the thing they want you to change. After my spouse died one of my friends called and said she'd heard I was having trouble getting out of bed and she was worried about me, for example. I told her that the intel was several weeks old, and it was more that I spent a lot of time sleeping in the weeks afterwards, that was just how my immediate grief rolled out at first. Maybe because I was so exhausted from the 24/7 caretaking at home.
