The world does not become less safe, it only feels less safe. Feelings are just information about ourselves and what is going on with us, not what is going on out there. The world is just you and me working together to make it work as well as it can. Sometimes some people like that T are not very strong (you thought you weren't the one who wasn't strong? That T is less strong than you!) or do not learn how to hold themselves so they can act in their own best interests and try to help others who are not as strong as they are. Your T has learned that and is helping you learn that. Your T is strong and able to help, rather than hurt you.

Yes, at the moment it would feel really good to live with someone like that all the time, to not have to do the hard work of therapy to become strong in ourselves but that would be a disservice to ourselves and our T, whom we love. Think of a chain and how it is only as strong as its weakest link; the chain that other therapist and his client were on is now broken. You and your T's remains whole.
