I'm kind of with what Granite says here. It is incredibly odd that the staff at a hospital would be in contact with potential psychiatric patients via Facebook, a terribly unsecure venue and a communication which is bound to be beyond the rules and procedures of the hospital. Beyond that, I'm not sure what to say as I just feel like I'm not quite understanding the entire story. Perhaps that is the jist of the problem with your T right now. Email communication about something this critical is just really loaded with the potential for misinterpretation on both ends. This really needs to be handled face to face or in the least, via telephone call where you can both get immediate clarification on questions you might have.
