Fear is a giant boulder that you roll in your own way. What's the old saying? "Courage isn't the absence of fear; courage is the ability to act in spite of fear."
These days, major media thrives on thrusting fear at everybody, from every single angle. It's not that you shouldn't be concerned about things, but you can't live with your soul tied in knots. You just can't.
As far as moving the boulder out of your way, just do the best you can, deal with the things you need to deal with and then move on. - Fred
