Like you I started open carrying for the job, but after a layoff I was so use to OCing that I almost feel naked without it.
I'm sure you know a lot of the laws but I'd say read up and remember the laws on OC should you run in to a civilian unaware to the OC laws and they ask you about it. Personaly I carry a copy of RCW 9.41.290 and 9.41.300 in my back pocket to inform civilians that do not know if they ask me about it, or should I need it for any other reason.
As long as your within the law you shouldn't be paranoid at all, should you have to use your weapon the last thing you need while trying to protect a love one or a 3rd party is to be paranoid or worried about what other think about you OCing.
If OCing counties to make you paranoid or nervous, maybe try CC if you have a CPL.
I hope that helps some.
