Oh, my, well, you know intellectually that you're not likely to be killed there. If this is your first visit, then you'll just be asked some questions, so the therapist/doctor can start getting to know you. They aren't really, really personal ones at all.

I have been to many such places over the years and I'm still here to tell the tale. Remember that you're going there to get help, just like you'd go to a regular doctor's office.
