For me it isn't that they don't/can't care. They may care, but when the therapy relationship ends it's over. The caring might still be there, but the relationship is over and it's painful if it ends very badly.

My old therapist did and said A LOT of the things you all mention in this thread and I did believe he cared, but the way he ended things has made me really wonder and the way he has acted after as I have tried to work things out with him. He seems so cold and unfeeling and uncaring now. I have ended up in much worse shape and much more damaged and confused and unsure of anything in life. I think at the end of the day we should learn that we can only depend on ourselves really. Trust no one. It's much less painful that way.
