Define apocalypse.
If it's societal destruction, that could be achieved with small things. Nuclear war, asteroid impact, getting hit by a corona mass ejection, etc. Human civilization is robust, but it is also very finely balanced. We are always on the edge of just making enough food for one/two years, none of our cutting-edge technology is time-proof, most of our knowledge can be lost precisely because they are stored on non-time-proof storage media and so forth.
Now, for an actual species level apocalypse, that one I doubt will happen unless it is some insane event, like the planet getting hit in the face with a gamma ray burst or getting hit by a comet that makes the asteroid that led to the extinction of large dinosaurs look like a pebble. Unless it is something that either wipes off the surface of the planet or alters the environment to such a degree that we had no time to adapt, humanity as a species would survive. Most people don't really think about it, but we are ridiculously hardy. We have conquered the planet starting from a tiny population and without any of the mountain of technology and knowledge we gained in the last century. If 99.9% of humanity were to be wiped out, I am reasonably certain we could do it again. It would probably take a long time, but we would still have a head start, so a few centuries should get the job done (though it would be a very different civilization from what we know).
As for how I would fare in an apocalypse scenario... Probably surprisingly well. I know how to farm and I have all the tools necessary to do it manually, without mechanized help. I am also familiar with masonry and carpentry, and I have the tools for that too, so I can build stuff if necessary. Finally I also have access to a gun in a country where gun ownership is highly regulated, meaning I could forage for food or defend my stash from scavengers if necessary. My only two concerns would be preparing food (I can't cook at all) and disease. Seriously, most modern people have no bloody idea just what a disease-free paradise we are living in right now because of vaccinations and health-care. Suddenly allergies and drug-side-effect won't seem so bad when you and all of your loved ones keep dying from dysentery, tetanus and toenail-infections...
