Stefan, never talked to you personally before.
But i would like to say that i deeply feel with you.
20 years ago i lost my mother by liver cancer. I know how it feels when you have to accept, that there is no point of return and you have to say goodbye.
Difficult to give a advice in such situation.
Try to let the time which is left to be "normal" as possible.
It helps the peoples who have to let go a lot.
The very best for you and your family! Be strong!
