Dan, it's been a bit scary around here, too. One thing I've found which helps me when I get full of worry or fear is to stop my mind, by saying or thinking, "I accept peace now." You could put your own words there i.e. "I accept God's healing love, now" or whatever you want, but it sure helps me to refocus and stay as positive as possible.
Much love and hugs to you and all your family including the dear critters.
