Take care of yourself, Susan, and hold the fort (inside). Do your best to let go of the guilt because you can’t control these things, nor can you live a life built around trying to or trying to keep up with them. It’s going to happen and it’s going to happen more. And, yes, there’s plenty in the water. Everywhere else too. Whether or not that has anything to do with anything is another matter. And whether or not you can do anything to control that is also another matter. At least you live in California where they give it a working try.
That middle ground is still inside you, remember. And you will not be "the last one standing."
