Apocalypse by default isn't survivable.
Probably I would try to enjoy the last 3 days and at the end I would repent because it would not hurt to cover all the bases.
If it would be survivable: I would not last long. Medical / vision / dental coverage is in short supply during the end of days.
Find a good fortress/ship with water and solar panels, download Wikipedia (annas archive), gather seeds and growing supplies, tools to fix stuff, duct tape: Realistically not happening.
