It is hard to see people we care about go through things like this. For some reason, at least for me, seeing someone I know struggle mentally is heart wrenching. Makes me feel so helpless and powerless.

I hope things turn out okay and that he is doing somewhat better. Hopefully he has a followup appointment very soon?

As far as somebody being able to hack facebook, why would anybody go through that much effort just to prank someone? Sounds very time consuming, posing as a whole friend's list worth of people and making cleverly thought out subtle little mockeries. And it would take a very special sort of person to do that sort of thing to someone suffering from post-craniotomy mental disorders.
