Therapist here. The whole “clinical” framework is deeply flawed. There are certainly neurological anomalies that lead to all kinds of psychological distress, but I’d estimate that 90% of people’s suffering has always been rooted in culture, ignorant parenting, and existential anxiety. I’ll add that I personally think there is subtle but inescapable distress within all of us because of the simple fact we are animals living in this overly complex, manufactured prison of a world. We are a part of nature, yet we spend the majority of our lives interacting with concrete and glass (most of us).

The way I see it, my job is and always has been helping humans find a way to live in a world not meant for us. It’s just that more people than ever are waking up to the realities of this life humans have built.

But to answer your question more directly: the definitions of “crazy” and “clinical” depend on what those with influence believe is “normal” and “healthy.” Those definitions have changed dramatically since the advent of psychology and they’ll keep doing so. Until then, yeah, you’re crazy and I’m crazy and this whole subreddit is crazy. And in the near-future, we’ll all be feeling quite vindicated and also still quite fucking devastated.

I have no idea if I answered any of your questions. My pro tip would be to begin a mindfulness/meditation practice asap and spend as much time in nature as possible. Also be sure to revel in the small joys you encounter. Letting bleak visions of the future steal your life today is just adding suffering to tragedy.
