Does personal experience in mental health issues help being a mental health counselor. Or you just need an understating in all issues and solutions on how to "fix" them and help cope mechanisms.

A separate issue is again about mental illness and the impact on individuals. Also that a diagnosis is not who the person is. I bring this up because of the stigma that unfortunately remains attached to any mental illness. This impacts some of the issues for the counselor who themselves have a diagnosis are, what if someone else finds out; do I disclose to the client, when and how much; what am I doing to take care of myself; and can I leave the clients' issues at the office. I myself have been in the field of mental health for over 45 years, prior to entering the field I have the diagnoses of Bipolar Disorder, ADHD, and PTSD. However, for the first 10 years of my adult life, I was in the USAF and had to hide the fact that these existed or lose my Top Secret clearance and been kicked out of the service. Again each person is an presents an unique picture also about how they perceive what mental illness is and depending on that perception will be the impact on treatment.
