Can’t answer about post chemo but all hands on deck is necessary and must be made clear. Simple meals maybe a few less veggies will happen but you get through - maybe a one on one chat with each starting with hubby who sounds like he is in denial.I am wondering if he has attended your appointments so he knows what’s going on -mine hates reading stuff but will come to appointments and listen / ask questions.Kids can be selfish and no notice we need help unless screamed at as they see us as invincible -my daughter told me she never worried as I was tough and had pulled thru stuff before.Its time to counter that belief and be a bit specific maybe even in dividing up tasks eg washing , shopping - maybe ask what night they might cook a meal but knowing kids the lion’s share will fall on hubby.
