The kind of empathy you describe is the lifeblood of this forum. Whatever aspect of life with Parkinson's you will find people here who are willing to share their experience and listen to yours.
While we are talking about practical things people can do.... several people here have reported the positive effects of volunteering for research studies. Newly diagnosed people are particularly attractive to studies that look for biomarkers to predict the onset of Parkinson's.
If you are over 30, newly diagnosed (2 years or less) and who have not yet started taking Parkinson's medication then you are just the sort of person who could help the Parkinson's Progression Markers Initiative
Details of this and other studies (including the small print) are at http://www.parkinsons.org.uk/research/get_involved_in_our_research/list_of_uk_research_studies.aspx
