I'm sorry you're having such a frustrating experience. But, sadly, I'm not surprised. I don't know how old you are. I'm pushing 70! And I've been kicking around the mental health system where I live since around the age of 50 or so. I've been hospitalized twice following major suicide attempts. I've seen a few therapists for brief periods over the years. It never amounted to anything.

I still have never been offered anything in the way of a diagnosis. I'm not on med's anymore. I do still have a psychiatrist I typically see a couple of times a year, just to keep my foot in the door, so to speak (except that his clinic has now cancelled my most recently scheduled appointment 3 times.) When I do see him, though, it's typically only for about 10 minutes. And about all he ever offers me is antidepressants & Klonopin.

My personal perspective is that once one reaches the age of 50 (perhaps sooner?) one just becomes excess baggage on the mental health railroad. Personally I've pretty-much just given up on the mental health system. But I hope your efforts to yet wring some kind of services from "the system" get you what you need.
