I was 44 when I got my first clear PD symptoms. We also went to some support groups and can relate to what you're both facing.
Talk to your PD nurse about what topics are coming up and ask if there are any other young onset and/or youngish long termers you could meet. You don't have to get on just because of PD so don't feel obliged to become friends.
I can definitely say that you do need some tips on what to watch out for and your true friends will be instrumental in keeping you on a positive track.
