Tree, a mother can have many children and love each one. Like mixed_up said, I don't think you can run out of caring. A teacher can care for each one of his students. Maybe it's the level of caring you're talking about. It's limited, but it's still caring.

I used to tell my T that she didn't care about me. She didn't like my saying that. She showed me in many ways how much she does care about me. She sometimes gave me articles from the newspaper about something I was interested in. Yes, she told me she gave them to other clients too. But that didn't make it less caring that she did it for me. I feel inside that she cares about me. I hope I'm not deceiving myself.

I don't think the T relationship can ever be just like that of a lawyer or other doctor. I know it's not from our end, but I don't think it's like that for the T either. I know they don't think about us as much as we think about them, but I think the caring is genuine.
