Psychology (professional and layman) has helped me immensely, but I also recognized it can be a trap. I had a therapist for a couple months help me through an intense depression, but I could also feel when it was becoming naval gazing, so then I stopped.
Psychology is a means to an end. But some people are attempting to make it an end. I do feel a cathartic release to get a 'diagnosis', but this catharsis is transient. There is infinite sub-categorizations to achieve infinite catharsis, but each further division, brings diminishing returns.
I hope that this trend is going to burn itself out. There is no promised land in medical psychology as popularly experienced. It can be used as a scaffold to leap into a higher self-awareness, but then it must be left aside.
