mgb, I understand how you feel. I've read around about this a LOT and from what I can see the "experts" as usual can't agree on anything much. Moreover there's a lot of shilling for the nuclear energy corporations, (downplaying it all), tech speak (which isn't especially helpful to we ordinary citizens right now) , some voices who seem to be knowledgeable and reasonable but are often more or less saying, "we don't know how this whole thing is going to play out and we're heading into a great unknown" and those who are in full panic mode.
I think we can conclude it's already bad and is going to get badder, but just HOW bad? From what I have read no one knows for sure.
It becomes a question for me then of what CAN we do?
1. We can store as much food and water as we can.
2. We can find covers for the doors and windows and duct tape in case we need to quarantine ourselves.
3. We can have on hand our basic necessities for at least several weeks, i.e. prescription medicines, hygiene items, pet food, matches, first aid kit, crank handle lanterns, touches etc.
4, We can get a small transistor and plenty of batteries.
5. We can have plenty of books and magazines to read if the electricity goes out. Games for the kids, cards and so on. It can help combat the boredom of isolation and make the days more bearable. Also I think the more you just "sit and think" the more fear tends to amplify.
6. Keep monitoring the news including alternative type news sites on the Internet, be vigilant about seeking out and finding information, stay alert.
7. Read widely for advice, especially from people who REALLY know what they're talking about (which to be clear is NOT me, I'm just suggesting what I personally would do).
8. Pray and meditate in whatever way is meaningful to you. I think it would be good to focus on what the Taoists call that "powerful force for good in the universe".
I know how distressing this is, but don't let yourself freeze or panic. Take calculated action. Hope for the best, prepare for the worst.
I don't really know what else ordinary people can do.
I know it seems like it might be another "Balrog" - "this foe is beyond you all" and that's so intimidating but try to keep calm. Really, it's the best thing you can do. Try to stay calm anyway.
