Paula,,
You have had such good advice and good wishes, I can only echo them. Unfortunately, I have never met you, but you can tell a person's character from the way they write, and you are trully a warrier, but a compasionate one.
You never know what is round the corner, and the cavalry could come yet. So many cases of peoplr beating the Doc's diagnosis, that it almost seems like the norm rather than the exception.
Carry on beingg an inspiration Paula.
best wishes
Ron
