Welcome to the club that nobody wants to join.
The ride is bumpy, frustrating, scary and requires patience like never before, but just take it one treatment at the time.
I went through , chemo , surgery, radio,a hip replacement and current on hormones ( only 51 ) in the last 18 months, so like a bucking horse, it's a challenge but hang on tight to your family and if your girls are old enough talk to them straight up, don't hide the details , it might save their own life being open and honest.
I have boys 25 &26 , they have gone to treatments, Dr's appointment, etc with me , never complained but have felt empowered that they can do something for you, it prepares them for life .
Best of luck
