I can imagine that getting an accurate picture of the funding available for Mental Health services is going to be difficult. Even if you were able to get the whole picture, many trusts would probably ‘Augment’ figures in various ways.
I think that it is probably like most people are experiencing, the services are still there, but they are not giving as much support. That, or charities are taking on the extra burden left by NHS cuts.
Neither of these things are long term solutions, they are only leading to the inevitable, a rise in mental health admissions to hospitals and police stations.
