My mom has a progressive pre-cancer illness. At some point it will develop into cancer and no-one can say how far off that is, though doctors can make an educated guess based on her other health factors. Once it's cancer it's not curable, and so it's called 'life limiting' rather than 'terminal' though the end result will unfortunately be the same.
I moved home to care for Dad who we lost recently, and I'm torn over whether to stay to be with mom or whether to go back to my old life. My mom has no wish to ask her doctors any questions about her illness and I respect that - if covering her ears gets her through then so be it. From googling she could have a couple of years, she could have ten. The information out there is very generic, and I'm not in a position to ask her doctor any questions without her consent. I also don't want her to become upset by asking her any more questions as she clearly does not want to think about her own illness.
From my perspective I'm trying to make a decision I won't regret later on. I know any of us could go at any time, but for other caregivers how did you decide to stay or go?
