The best thing you can do is to stop worrying about all this shit

Like it or not we’re at the end. Prepare yourselves and your families.
Get food, sleeping bags, water, guns, ammo -a lot, and get more. Get more for the people you care about that won’t.
Get a Bible and really read it. - there’s a lot of shit in there that no preacher will tell you about.
Endure till the end.

One more thing. ..don’t pull the trigger without saying a quick prayer, then you’ll know if it’s ok to do it.
