Hi Sara,
I'm 58 and was diagnosed at 56. I, too, was always very active and now I find learning how to live well with this is challenging. I work full time, but just this week I am cutting back to 4 days - I'm too tired all the time.
My Grandmother had this, so I kinda knew what to look for. A long time ago I went ahead and identified Drs "just in case" So my diagnosis was easy (luckily) and getting to a supportive doctor was easy too. So I have had no physician problems. Even my GP is supportive.
As far as acceptance, I think I am relatively accepting on my own behalf but I think that's because I spend so much energy trying to get other people to accept it, MY acceptance is a forgone conclusion.
New things to replace some of my old things? I'm still going to my Toastmasters group - I figure it will help with my slurred speech. I'm trying to exercise more but that was never my thing. I found I really like water aerobics, and I can't fall very far! I signed up for a Learn-to-row program in the fall because it will be great exercise that is done sitting down. I'm trying to find a sailing program for physically challenged people.
I've finally located a hippotherapy program. I love horses and I used to ride a little. It's part of occupational therapy and I like riding so I am eager to start that. You may find a similar barn near you.
I've applied for a balance therapy dog but they warned me it will take years to reach the top of that list.
And I've started a "Vision board" . Its a large cork board hung in my office for me to pin pictures to for inspiration. Of course, there's Pinterest on the computer too.
And I can still crochet without too much difficulty. I know that one day I won't be able to, so I am crocheting baby blankets for my grandchildren NOW to save for later (I don't even have any grandchildren yet).
I wish I could travel but everyone I'd like to travel with is too busy to go with me. My husband would like to but always "next year" but I worry that when next year comes, I won't want to or I won't be able to enjoy things. I have thought about finding a travel organization that I could go with.
Hope this helps! I'd like more ideas from everyone else too!
