I don't think it's about right or wrong. Therapy failed me-- I got some good stuff, eventually, processing what had happened by myself and with input from this forum. But it took far too long and did harm along the way.

Real trust, it seems to me now, involves a balance. I can trust in some good stuff and be cautious about some other stuff. And change my opinion, change my feeling, about either as things change in what I observe in the world.

Ultimately -- trust in yourself is what is needed, I think. Trust that when you trust it's for good reasons and trust that when you doubt, there may be something there to look at and take into consideration, too. If therapy helps you with that, then good for it and good for you!
