Oh @Halla,
Totally get this. I experienced this. Im sure others do to. People dont react the way we think they should. In 9 months of treatment my brother rang me once and visited once. I saw him occassionally at family events and i was hurt that something so big for me had so little weight to him and he just carried on as if nothing was different. I dont think he even noticed my distress.
I dont think age comes into emotions and values and expectations.
This is a big experience.
I just worried about getting well during treatment and let other things slide. There are a hundred emotions i experienced intensely. It was a relief in some ways when i did this. But...
I had to reenter my life at some point.
