Because we don't have a clue on what exactly would happen, this is a very difficult question to answer.
A lot of people suggest to stay where you are, but that's not always possible. Lets say, for whatever reason, you have to leave the comfort of your
home immediately. The first thing you need to do is quickly round up all your family members. Most pets are an absolute NO. They would cost you much
time and resources. However, if you have a dog who can walk without a leash and might be able to kill (small animals) to eat and sniff out water, for
all means bring him! He might even be able to help you with finding food and water. Sadly, most dogs cannot do this, so your best bet is to let them
free, let them live their last days with Mother Nature.
The next thing you need to do is tell your family to grab everything possible. You should have already stocked up and things like non-perishable
foods, water bottles, backpacks, windup radio, heavy clothing, blankets, weapons, money, dummy wallets, outdoor tools (like shovels), buckets for
water, and probably the most important, matches. Matches can boil water, cook food, make warmth, light, scare away others, and can be weapons. You
should have made a meeting spot, like by the mailbox or something, because you need to meet up quick. Once everyone is ready, GET OUT OF THERE! Don't
even try taking your car - there will be no operating gas stations and the streets would be jammed with cars. Best go leave on foot, or maybe even
bicycle, of you can manage. Keep in mind you will have to abandon the bike at some time.
You need to get as far away from that place as possible. Your best bet may be away from civilization. Also, if you happen to stumble upon someone you
know, tell them to join you, the more the merrier. I would head for the woods. Here you have many resources and are away from the big rush of people
in the city. Once you have been traveling for a long time, setting up camp every night to get rest, try to find an abandoned building to stay for a
while. If theres an operating airport nearby and if you have enough money, you need to fly away. Your best bet is to ask around and find the least
corrupt place possible to go, even if it means a new country. Go there and find a place to stay, but don't get too comfy.
Lets say you weren't able to fly out. You should get the the calmest place possible and try to settle a bit there. Hopefully you brought a shovel,
because it might be best to go underground. A good place to be would be a sewer; they're very stable and hidden.
As for what happens next, you may be completely on your own... Try reading a few books on survival, that should help.
