It took me years to come to terms with it. It did not help that in the beginning my diagnosis bounced like a super ball all over the place. When the doctors cannot reach consensus how can you reach acceptance. For you specifically give yourself some time research and ask questions to gain understanding. With understanding comes the ability to have acceptance of something as permanent as Parkinsonian Diseases. We all take a lot of time accepting something that is permanent and progressively damaging. Give yourself some time my friend.
