So... how do I, a "normal" person deal with the worrisome part of what I may be able to control?
I... don't.
If I can control a little aspect of something and I want to do it and it's not against some sort of rule... then I do it.
If I can't control it, then I don't.
If it's something in between, just use the societal rules and be content to know that you did your best, given the information you had available - where "available" may mean only information that you could remember at the moment of decision... and forgot a lot of things which could have generated a different outcome. It didn't, tough luck!
There's an old saying: it's no use crying over spilled milk.
