When it's something like this, that doesn't directly impact my life or my loved ones, my first step is to take a deep breath and break the news cycle - walk away from the news and stop the mental and emotional barrage. Second is to spend time with my kids and husband and reassure myself that we're all safe and sound. Third is to confirm that we're as prepared as we can be right now for the realistic threats in our AO, and that those threats or the potential for them hasn't actually changed because of this, even though it might feel that way. Rinse and repeat as necessary.
