No human is perfect, I am sorry to say. Everyone makes mistakes. Simple. It doesn't make you a monster

Most likely they wont though, they know they are supposed to keep things confidential. They are well aware of laws and ethics. They do have certain things they have to report though, like harm to yourself or others.... I believe. Or a intent to harm yourself or others it might be. You can always ask them about the specifics of what they are legally bound to tell someone if you bring it up.

I personally wouldn't care at all if my T put out a an ad in the paper about my life, it's not that interesting or secretive. I wouldn't care, but I know he would never do that and I know most people are not like me and it would bother them. Anyway, just gotta trust them the best you can, it's hard because again, humans are flawed.
