@rozie83 You are one year ahead of me, I'm 83.
You have had some very difficult periods that in my mind were probably quite difficult and stressful periods .....and as we live life have to learn that all is a part of living life. Reality can be so surreal.
I have not had children but I do know enough to know how difficult it is when we have a loved one in poor health and the horrible heartache we live with....... with the loss of a loved one.
Yes it is hanging over his head at such a young age and also 'hanging over your head'. May you both, and all, find your ways to managing it all in all ways.
