I have mixed thoughts on therapy, I started it a few months ago (my health care provider offered me free therapy, yippee) and the most helpful things my therapist has done for me is recommend me books that go in depth into a subject.
There are some things I could never tell my therapist bc I know they'd try to "fix" me (namely the fact I'm plural), and dealing with that would probably do a lot of harm. I can't tell them about any self-harming thoughts because I'll be institutionalized. But it has been helpful to work through understanding my abusive relationship, how to deal with anxiety, how to navigate my relationship with my parents in a safe way that won't get me kicked out, etc.
Basically I don't know everything about the world or myself and having someone tell me what they know is useful, but the interactions also inherently feel somewhat adversarial because of the aforementioned reasons, which limits the effectiveness. I sure as fuck wouldn't pay money for it, lol.
