Waiting room of horrors

Usually the only other person who shows up at my doctor's waiting room.  We both follow waiting room etiquette and ignore each other.  Well he didn't show, a new patient did.  Apparently my answering her question about which button to press was an invitation for her to tell me her life story.  The most entertaining part for me was her assumption that people who go to therapy go because they have either a substance abuse problem or a "domestic situation."  It was really strange to be talking to another patient who was making such assumptions, that mental health is limited to addiction and as a companion to 12 step programs.  She told my three, no wait, four, different programs she was currently involved with.  She invited me to come along.
I was debating if I should tell her I was there to deal with anxiety/depression issues.  A part of me felt that it's none of her  business and she should know better than to ask, another part  didn't want to say anything because I was worried she have the "well, that's not such a big deal reaction."  Shameful, I know, I'll talk to my therapist about it.  She also asked what traumatic, life changing event made me decide to go to therapy. There really isn't one, it's more that I finally got decent insurance that actually lets me see a good doctor.
Anyway, I was so happy when her doctor called her in.  The worst part is that I had picked up the March issue of Details and wanted to read the damn thing.  They written a profile about the blond pony-tailed guy who sale bizarre exercise equipment.  I guess it'll be waiting for me week...*sigh*
