I was diagnosed in December 2013 (I am 52) and am still stunned more than in denial as was told by my GP that my tremor in my left hand/arm was not an essential tremor and was NOT Parkinsons. When I went to see the neurologist, she did various writing tests then got me to walk up and down the corridor then sat me on the bed and got me to do various physical tests then said I had Parkinsonism, my girlfriend who trained as a nurse was stunned with the fact I was diagnosed after 1 consultation.I knew something was not right and think I just expected to be given some pills and for my tremor to go away. Finding it very hard to come to terms with the fact I have something that is incurable(at the moment) though not life threatening itself, don't know if that is a form of denial but I guess it could be.
These forums are a good source of information and a source of comfort from the fact that nobody is alone if they don't choose to and if you ask, there always seems to be someone who has been through what you are struggling with so do not be afraid to ask, however trivial you think your question.
Hope this helps and good luck with your journey, there are lots of us on a similar one.
