To the OP: to my friends I'm apparently super paranoid (just in general), and your level of paranoia makes me wonder how you got into bitcoins in the first place... cough...silkroad....just kidding. But you will live a much longer, happier, truly richer life if you could turn your paranoia into "ok, so I made it really secure" and then just STOP thinking about it. That's what works best for people with OCD, and it works for everybody else, as well.
