Maybe it's because I have dementia in the family (so probably in my genes), but my GP's taken my concerns about my mental health seriously. I don't have any memory problems at present, but she agrees I need to flag up problems as soon as I suspect them, to be referred across to the specialist mental health team.
When I first raised it, I said I knew about the research linking diabetes with the condition, and the GP seemed to accept why i was worried. So does it depend on how we put the problem - and fears and concerns - to them? And choosing the GP to talk to? I talked about it first with the diabetic nurse at my GP practice, and she recommended two of the GPs in the practice who she thought would be the best ones to talk to about it.
