My T/pdoc also has the 911 thing on his message. Perhaps your T changed the message because she is trying to get all her clients (not just you) to start being aware of the other resources available as she will be gone soon and not available in an emergency.

As for the facebook, that is surely just a coincidence of timing. He could have changed the privacy settings for a zillion reasons...hiding from a crazy ex-girlfriend, an annoying old college buddy, that guy from 3rd grade who wants to sell him life-insurance, the other guy from 3rd grade who wants to borrow money. It is not because of you.

Breath in. Breath out. Repeat. Your T will be happy to see you tomorrow. Be happy to see your T and soak up some T love.
