Multi - exactly. But that's when we get into an impossible situation with nobody understanding anybody and a larger percentage of the population relying on a few. Society is collapsing under the weight of this.
Also - interesting - 30 years ago I was working with pharmaceutical researchers and marketing teams. They were targeting two groups of people: recently bereaved and cancer sufferers. They participated in millions of pounds worth of conferences and campaigns and Dr /Medical seminars to convince the medical profession that cancer sufferers had a better outcome if they kept a positive outcome and recently bereaved coped better if they could get on with a normal life. (Possibly true). Anti-depressants were sold in tonnes. "Depression awareness" was actively supported by these companies.
Within a couple of years they moved on to elderly care and post-natal depression. Every old person who was lonely and losing friends and health was diagnosed with depression. Every new mother took a depression test. It was a calculated drive to increase sales of anti-depressants. (Good sellers as people tended to stay on them for many years)
I am not saying that people who are depressed are imagining it. I am absolutely not minimising . I am just saying that it is always worth looking at the wider picture.
The OP raised a topic worth talking about. Most people have just jumped and dismissed her.
We do need to change the way we live but that will be difficult with the prevailing attitude.
Food choices, work choices, exercise, decent housing, economic security, debt, family bonds, community structures all play a role in mental health. We need to examine these as a society and as individuals and see how we can make it better.
Anyway - sorry if I have offended anyone. I just think that MH is too complex a matter to be trivialised in the way it currently is.
