Are psychologists more immune to psychological problems?
Does knowledge of a psychological problem prevent (or enable one to better defend) the development of psychological issues? For example, if a person has studied about depression and is familiar with the causes and cures of it, is that person more able to prevent himself/herself from going into depression?
Are there statistics about the ratio of mental health problems among psychologists and therapists vs the general public?
Having a molecular understanding of the psychological problem aids in one being more able to cope with that specific problem. I have known therapists who have experienced the symptoms of a psychological problem themselves and take steps to proactively manage their symptoms. It would be difficult to obtain the statistics of the ratio of mental health problems due to HIPAA regulations and the most likely under-reporting from the stigma of having a mental illness.
