I suppose this goes hand in hand with recent raising 'awareness' of mh issues and 'equality'. Both are insufficient. If people are only informed on a casual basis then they pick up only a surface understanding. They don't 'get' the full horror in the same way as they don't 'get' suicide. They don't want to. It raises too many question marks over the education system, the medical system, the media, our society in general. No individual can change that.
So most people don't think too hard. They don't want all that struggle in their own lives. And some will live vicariously, dipping into the 'mad-genius' concept; van gogh, kurt cobain, sylvia plath, robin williams, with this surface understanding. A single MH episode can be viewed as rebellious and edgy. Its no surprise that many artists struggle with mental health and are 'successful' outsiders when success is measured in capitalist terms only.
If mental health awareness is leading youngsters to an mh issue 'tribe' is that any different from all the other tribes ever? Even if some are imposters, others will find support and help. Is the 'identity' that brings good or bad? Impossible to generalise I suppose. Generalising is always the wrong way to go.
