My thoughts are with you Alygran... Its a difficult time.
Am a bit mindful of the fact I seem to be posting on all sorts of different boards with first hand knowledge but sad fact is, when you get to 64, you HAVE experienced most of what life can throw at you.
Sheila: 20 years ago, MY best friend of 30 years was diagnosed with cancer at 42. I helped her through it and was there at the end too. All she wanted was for people to just be themselves - not to treat her differently - talk as they always had done. She was upset that so many people felt they couldn't visit as they didn't know what to say!
We laughed, we cried, we planned her funeral together....I let her lead in it all. I saw her wishes carried out.
Unknowing to me she wrote me a letter, which I was given after she died, and in it she thanked me for 'always being me' She said the laughing we did, was so special and she was glad she could talk openly about her funeral (cried buckets after reading it mind you)
Of course, everyone is different so yes, just be guided by your friend but don't treat her like she is any different to the person you have always known.
My thoughts are with you and your friend at this difficult time.
