I had a dysfunctional life. But I was too macho to seek help. So for 30 years, I lived through a mild state of depression, thinking that I was OK.
A confluence of strange events happened for me to seek help. I had three sessions with a trained counsellor. This fellow did a fantastic job and helped me understand the world--and it wasn't my fault. I felt a lot better. About a year later, I forgave my transgressor.
Once in a while, depression does settle in. When I recognize it, i can usually think myself out of it.
Sorry to hear your difficulties in finding a capable professional. Psychology is a strange science for there are often too many possible interpretations. It's good you did some reading.
