I heard a BBC journalist the other day referring to people who were 'suffering from mental health'!
In the same context, some politician was looking forward to the day when admitting to 'mental health issues' carried no more stigma than admitting to having sprained one's ankle. I'd have thought that an important step in 'normalising' mental illness was in fact to call it just that.
It reminds me of the attitude to cancer when I was a boy. The word 'cancer' conveyed such terror that it was avoided whenever possible. Things have changed, thankfully. Perhaps the same needs to happen with 'mental illness.'
