The old routine is completely impaired of course. But the new routine isn't an impairment or even inferior, except perhaps to some societal / corporate norms. But these latter are perhaps best shrugged away: an HR dept, or society, can impose their norms all they want but that isn't going to enable you. Other people's opinions matter less when you've faced that your time is finite anyway.

That doesn't mean being selfish; it just means you have to focus on finding a path that works for you and shedding unnecessary constraints. Make it work and do some good with the time you have left.
