Could you take a 50% contract, and claim 50% social benefits? These last 50 won’t be much but will help.

That’s kinda what I do here in France, but I only get short contracts, then unemployment, then work etc to about 35~55% a year.

Another thing that helps is not going 50, but like 80 - it helps a ton to have 2 afternoons a week, I have many friends who did / do that.

My mother was a nurse, I feel you. Took early retirement as soon as she could.
