I don't really think there is a stigma concerning 'mental health' - people are talking about mental illness and mental health all the time. In my line of work at least, there are excellent supports for people with different kinds of temporary and lifelong challenges falling under the umbrella of ‘mental illness’.

However I don't think we are speaking truthfully about the deeper causes of mental un-wellness. I still see the issue of depression and suicide framed too much as an individual issue when we need to discuss it in terms of our society's failure to meet BASIC HUMAN NEEDS.
