It's worth taking into account the harm that can be caused by diagnoses.
When I was young, I was given all of the above diagnoses by 'experts' who were paid by Nfather. His agenda was to claim that I was born with an abnormality so that his decades of neglect and abuse could be covered up. That was actually the time that I stopped interacting with my Nparents. I learned just how dark Npeople are.
In recent years, I was diagnosed properly with C-PTSD, which was actually helpful since it explained how being around abusive parents, sisters and schools progressively damaged my nervous system that is literally at the centre of all functioning as a human.
But back to my original point. As soon as there is a lack of quality guidance and mentoring, suddenly all sorts of little psychological molehills become mighty mountains.
