Since her announcement Fiona has been vocal about continuing on with her life as best she can and helping others.
She added: "People have been so kind to me. I was anxious people would be staring or whispering about me or would just write me off as a batty old woman. But there has been incredible kindness."
Speaking to The Mirror she said: "This disease has ravaged my family, and now it has come for me. And all over the country, there are people of all different ages whose lives are being affected by it - it's heartbreaking.
