I'm 66 and live in Yorkshire.
I was diagnosed 3yrs. ago and like you, struggled to come to terms with everything. My neurologist said that by the time symptoms show, I've probably had it for decades!
I read up on PD by googling it and reading posts on this Forum, which helped a lot......although sometimes a bit scary! The frustrating part of having this disease is that it can affect everyone in different ways at different times. No-one can actually tell you what's going to happen to YOU.
I have accepted therapies on offer....physio, psychology and had a 'home visit' from our local Support Worker, which was very helpful. You are very much left to be in charge of your own future and how you cope, I have found.
Stress and lack of sleep make the condition worse. I have recently been practising the art of Mindfulness, which is very relaxing.
I hope all goes well for you......you are not alone.
