Dear Ian
I was so sorry to hear of Litty's passing and send my condolences. I often used to see her posts and comments on here.
I lost my husband, who had cerebellar ataxia, last October so appreciate what you are going through. Not only have you lost a loved one but your role as her main carer has disappeared over night.
I wish you all the very best and think it fabulous that you have the strength to want to help others in their hour of need. Your expertise and experience will be invaluable in educating and supporting both professionals and those afflicted with Ataxia.
