@LisaO you mentioned your children are not dependent on you now. Are you kidding? There is no age your children will not want you to be there. Ask them if you dont believe me. Just cause they are getting on with their lives doesnt mean you are not important to them.
What a gift you were given by your Gp for recommending a mammogram. It looks like its not your time to go.
Have chemo and live a long and happy life afterwards.
I know seeing what your mother in law went through would have been very hard.
Guess what you are you.. give yourself a chance. That cruise you planned is waiting all that different is the dates are changed.
How do I know things will be better. I dont. I do Know that approximately 14monts later after all treatment etc I am now cancer free and looking at cruise brochures. You were given a gift take it life is precious.
