Your idea of a flat nearby is a good one. I wouldn't think living with grandchildren is very restful for you. It has been good of your daughters to have you staying with them, but possibly a bit stressful all round. Find a nice place in which to do as you please, close to family and doctor/hospital.
Best wishes for a continued recovery and peace!
