Hello Neil
Getting a disability pension for a mental illness is very difficult, you have to have a mental illness that is assessed as severe according to their tables, if you google disability pension tables you will find them, the illness has to be diagnosed treated and stablised by a psychiatrist, i think maybe clinical psychologist can do it also, but they can not prescribe medication, you have to have tried all reasonable treatment, stabilised means the illness is stable in its current state, meaning it will not get better in the next two years, it is best to have a psychiatrist help you, and best if the psychiatrist can address the impairment tables in their report and say if they think the illness will or not get better in the next two years.
