Sorry to hear that Rosannie - my OH has PD and was diagnosed about 8 years ago, but had already had symptoms for about 2 years before that.
The medications he takes are a bit of a nuisance - remembering what to take when is the main problem (as he also has drugs for his heart problem) - but they really do keep the disease at bay in a way that never happened in the past. He does of course have some problems - lack of stamina is top of the list. But he can still play the violin, even though he has a tremor on his left side, the hand he fingers the violin with.
No-one looking at him would have any idea that he has PD, as he does not shake badly.
There are of course all sorts of minor problems - the disease slows down his gut, so he is often blocked up, he has a bit of giddiness etc. There is a brilliant Parkinsons specialist nurse in this area and she is on the end of the phone for either of us anytime.
I am sure that the condition will be kept at bay for you in the way it is being for my OH, so please do not feel too daunted by the diagnosis.
