I am an unrepentant FR addict and will probably never seek out rehab but your lack of contact with John sounds more concerning to me right now. Family is everything. Is there no one you can call upon to go and take a look for him in person?
Wishing for the best and a speedy reunion.

Sons are so different from daughters. Daughters call. Sons do not call (broad stereotype). All my friends and I who have sons tear our hair. They don't see what is the big deal when you finally determine they are alive.
