Oh Maggiebee! - I am so very sorry. It's horrible, but life's like that. I learned a long time ago that the light at the end of a tunnel is usually an oncoming train. It doesn't know when you have had enough.
I'm lost for words.
I have to write a card to post tomorrow, to a friend whose Christmas card told me that her husband (health-freaky retired G.P.) has been diagnosed with a brain tumour and has been given 3 months.
It's a shock to understand that you aren't in control - I know that one of old.
This is where you have to release control and learn to live with what happens. In my case, I am fortunate in having a faith, which helps me to cope.
