And we also have to know ourselves. For instance, if I know watching Law and Order: SVU upset me because it deals with sexual assault in every episode, but I go ahead watch an SVU marathon anyway, I have sort of set myself up for whatever upset that causes me. I have to take better self-care than that.

I have no idea if the OP knows she gets easily upset by things or not; I don't know if the OP is dealing with transference issues that might be easily stirred up by new information about her T. But it that is a possibility, staying away from digging up new information that might set that kind of upset off would just be good self care.

Sometimes just because we can do something doesn't mean it is the best thing for us to do personally. Some people can look at information about their T all day and not be at all phased by it. Others may need to think ahead before they leap. My guess is the therapist is more concerned about the effect this had on the OP than on his privacy.
