Why are school psychologists/counselors so unhelpful?

For context, I've been to my school's psychologist a couple times because i'm messed up in the head, but honestly all those missed classes and sessions i had with her we're completely useless. The first time I went to her I told her everything I was struggling with, and all she did was ask me some questions that didn't even lead to anything. When I went to a psychologist outside of school, there was a GIGANTIC difference. Now maybe therapy stuff jst doesn't work for me, but her session's didn't help me in the slightest. All of our sessions were focused on her asking a bunch of questions, some that even seemed kind of unrelated. Why is this??? And in case you're curious, part of the problems I came to her with WERE school related, so i really don't know.
