What is the reason why Mr. K, a famous psychiatrist , condemned the doctor of SHINee Jong Hyun?

* Part of Jong Hyun's will:

I was asked by my doctor to find out why it was painful. I know very well. I am in pain because of me. I am the one to be blamed for all of it. Doctor, did you want to hear these words? No, I am not doing anything wrong. When I was told that it was due to my personality with a calm voice, I thought being a doctor was very easy.
