This is just loaded with cliches and I certainly am not poh-poohing your fears. They helped me. I would love to help you.
Breathe Twise! Give thanks! Enjoy every minute of that "normal" life. Isn't normal wonderful?
Now this is all easier said than done but try to, OK?
Don't get too high don't get to low. It's corny I know but but go for "one day at a time". Worrying is imagining the worse to come - when fears come up replace them imagining good.
You're on it. Your wife had good care with good results. She will be monitored - if something else would come up it will be taken care of.
I don't know about expressing your fears to your family. I was not in that situation. But go ahead and use us here. You described the outcome as miraculous but made no mention of Faith. Whatever, I will also pray for you and your family. Faith in God is what got us through.
