Well as a mental health professional I would argue that although there is not enough support for those with mental health problems, the UK has in fact one of the best mental health services in the world. Take a look at the rest of European or us services, or even in Ireland (where I currently work). The resources are not there at present in the UK, but the quality can be exceptional.
Regarding Wesselys quote, I whole heartedly disagree. We know already that men and BAME populations have significantly lower engagement rates in mental health, and particularly men are most at risk of suicide, so we need greater information in the right channels to try and open up a dialogue with these groups. Rates of referrals are always high, specifically in secondary services that I work in, however the threshold does not change and we will not work with people without a severe and enduring mental health problem. At the end of the day, mental health is not a box to fit in, it is a spectrum which are all on all the time. Not everyone needs support, but greater awareness may help in educating people so they know when they do, they can reach out to someone like me.
