Cancer is enormous...not just to your body, but it does a big number on your head. Anyone with such a devastating diagnosis is perfectly entitled to deal with it in the best way for THEM. Family members have no bloody right to be annoyed, to have expectations or to question how you deal with it.
Tricky to underplay with chemo, but with my ops and radiotherapy I kept it all low key, no performance, minimal discussion, no more significant than getting my eyebrows waxed etc etc I only spoke of follow ups to relay the outcomes....positive so far.
The reason for this was not to save my family from anxiety or concern, it was to save me from having to spend any energy in re-assuring them. I need all of my focus to be on making ME feel better, not anyone else.
