”So how do you think mental health problems begin?

Only just seen your question RD, and I’m not sure who it’s aimed at. If me, I’m a retired accountant so I don’t regard myself as qualified to answer it. I do, however, have a very close relative who has suffered very badly from PTSD as a result of his service in the armed forces, and in the police forces in the UK and in Canada so, when someone claims to be suffering mental ill-health, I tend to give them the benefit of the doubt until it’s categorically proved otherwise.
