Having worked in mental health I find this to be very true.
“All of the diagnoses that you deal with – depression, anxiety, ADHD, bipolar illness, post traumatic stress disorder, even psychosis, are significantly rooted in trauma. They are manifestations of trauma. Therefore the diagnoses don’t explain anything. The problem in the medical world is that we diagnose somebody and we think that is the explanation. He’s behaving that way because he is psychotic. She’s behaving that way because she has ADHD. Nobody has ADHD, nobody has psychosis – these are processes within the individual. It’s not a thing that you have. This is a process that expresses your life experience. It has meaning in every single case.”
