It's good to hear from you. I get stressed out whenever my father, who is now 72, has a problem. Have to remind myself that a Marine, and retired cop can handle these things, but I still worry. I hope your Dad is OK.
I have a serious fear of getting my teeth worked on, so I know how your other half feels. Novacaine doesn't work on me, so it always hurts.
To your friend, and your nextdoor neighbor, I wish them well. A broken arm, well, hurts. Don't ask me how I know. Just try to remember that stressing out over others won't help them, but the stress will feed IT, as Oluwa calls it. It's hard to not stress over those you care about, I know. Let us know how things go for you, and for your Dad and friend and neighbor.
