If you don’t have a strong local community you participate in, join one, or start one. A far-flung online community is only as good as the power supply/internet network.
Learning survival skills is good, finding people who already have those skills is a lot better. You do not need to move to start growing vegetables and keeping chickens and rabbits unless you live urban; suburbs are mostly wasted outdoor space. Start a community garden. Organize locally. Don’t shun people even though you find them difficult. Everyone has something to offer.
If you can’t think of what YOU have to offer, now’s the time to figure that out. Learn a practical skill, like plumbing, or butchering, or fixing tools. Something people really need.
If at all possible, join a church. Of course avoid the psuedo-Christian neo-nazi ones. Churches are built-in self-help communities. They feed the hungry, clothe the frozen, care for the sick and elderly, they look out for the lonely, the frightened, they give sanctuary to immigrants and refugees. Even if your local churches are ineffectual at some or all of these things, they know that this is their literally God-given mandate, and if things get hairy, they will already be organized and willing to take action.
If your community is full of hate-filled bigots who dominate and bully everyone and control the local government, well that’s a place to move from. They will take care of their own, but they will stomp you to death. Leave.
