My dad who I am very close to has just started chemotherapy for a non curable, but hopefully treatable cancer. Outwardly I hear myself being all positive but inside I'm crumbling. I never expected it to be so hard. He's not good at remembering meds so I have set alarms on his phone for when he has to take them all. I can't stop googling, and thinking about how long he has left and what the side effects of the drugs are. How do I calm down?
