Obviously there are differences, but I have seen people here (a few times this week) and elsewhere suggest that therapy and other relationships are basically same in terms of potential for bad endings, betrayal, hurt, rejection, etc.

When someone reports that therapy has ruined them, there are standard rationalizations given... e.g. nothing lasts forever, relationships are hard, therapists are only human, you can't really trust anyone. Have seen it over and over.

Rarely does anyone say -- you are hurt, partly or largely, because the unique nature and structure of therapy is such that serious emotional pain is a high probability outcome.

When therapy is being talked up, the differences are emphasized, though only those differences that help sell it -- e.g. it's a safe space, all about you, therapists are well-trained, therapists don't judge.

I consider those differences to be mostly pure bullsh*t, and the differences that matter are those that are not acknowledged and that lead directly to damaging effects.
