Other writings: For example the books by Vivian Broughton, a UK therapist: https://www.vivianbroughton.com/my-books/ Her latest book ("You were just a child...") contains critical essays, which you might enjoy.
Essential reading: The books by Judith Herman, who coined the term "Complex Post-Traumatic Stress Disorder" and lobbied to get it added to the DSM. Her latest book is all about justice for victims (and how the system is failing them).
The most famous critical essays about modern society from a therapist are by Sigmund Freud. You may want to start with "Civilization and Its Discontents" (1929). Quote:
"The present cultural state of America would give us a good opportunity for studying the damage to civilization which is thus to be feared. But I shall avoid the temptation of entering upon a critique of American civilization; I do not wish to give an impression of wanting myself to employ American methods."

Various texts by other psychologists linked to at the bottom of that page.
My experience matches very much with this thread. After years of therapy I hit a limit to what conventional psychology could explain or understand or “treat”, and the only thing that worked after that was going deeper into my own psyche with meditation.
The whole psyche is available for exploration when you stop believing that you are made of thoughts. It becomes extremely clear where all the anxiety and depression and addiction comes from, and that almost all conventional approaches merely treat the symptoms.
