Matthew, you're being tongue-in-cheek, right?
Breanna, I think Vic's thoughts are sound. If you live near fresh running water, and are out in the country, your approach will be much different than if you live in an urban area. In the latter you would need to have water stored – a gallon a day per individual is good, though half a gal would suffice – for two weeks, is minimal in my view (note: I've had the store-bought gal jugs leak in storage, so better commercial grade containers are best). If you're in the former situation – in the country – your need for storing water would be different, you would just have to make sure it is free of contaminants. There are survivalist / prepper sites that can give you info on what foods store best on the long-term (for example, brown rice – which is healthy – does not store long unless it is frozen or refrigerated; the oils in it go rancid, so 6 mo tops), and as Vic pointed out you need to have a balanced diet. If you live in a rural area, and plan on remaining in such – even if you change lodgings – it might be well to learn to shoot and hunt, both larger game (deer, bear, wild hogs if those are around, etc) and small (birds, rabbits, ground hogs, etc), and have the right firearms for each.
You might also want to prepare for loss of electricity and fuel for heating and cooking. If you are on country property you should have wood available; if not you should seek what type of fuel for cooking & heating would suffice. The same goes for staying warm clothing and bedding-wise. It might be prudent to get some ECW (extreme cold weather) Army surplus sleeping bags, but these would be for sheltering-in-place as they are heavy.
If you have spare funds, buying junk silver (pre-1964 silver coins – including 1964), which are 90% silver and would be a viable currency of exchange if the dollar lost its value (actually it already has, but if all confidence in it evaporates and it is worth nothing in stores). Silver is low now, so it's a buyer's market; ditto for gold, but that's for those with dollars they want to exchange for the preservation of their capital. Many are down on silver and gold today, but that's my 2¢ , and I've been pondering this for a long time.
You might want to get survival items suitable for wilderness backpacking, tent, knife, axe, rope, tarps, light cooking gear, etc; also a radio that runs on solar / crank / batteries / and wired electric. You would get more ideas at the prepper sites.
And what Vic said about community is essential! This would probably include your immediate family, and your church, and other close friends. It will be very important to have such close people around if some emergency situation arose; one should also have contact info for such people, and a pre-arranged meeting place, in case all communications went down.
Last but actually first in importance, is to have – and continue cultivating – an intimate walk with the Lord Jesus; be part of a sound Bible-believing church; know the Scriptures well (have spare Bibles set aside in case you lose yours).
Also, a good comprehension of what might be coming down the pike, eschatology-wise. Personally, I think this country – America – is due for heavy judgments from a profoundly offended Deity, and these may come in the form of natural disasters, attacks from other nations – perhaps initially of the cyber variety, as in taking down the electric grid, or the unleashing of highly contagious biological weapons, or chemical weapons – and later in the game, more extensive and destructive attacks. We should also expect to see domestic disorder – food riots etc – and government responses including strict martial law. We should also prepare to see our government change radically, no longer the benign entity it once was. I think the Amillennial school has by far the best take on the book of Revelation's visions, symbols, and prophecies, though it is a difficult area due to the other "schools" clouding the air with confusion and misinformation.
Eschatology is a pastoral matter to me and not primarily an academic study, due to how getting it wrong can make a mess of one's expectations, preparations, and labors for Christ and His gospel.
I hope this is helpful.
