Well, after reading ALL of this...it sounds like you told the nurse what she did and she was unwilling to apologize/say she made a mistake? That's not cool!
In any event...i'm sorry you had to suffer this way Angela *Hugs*
Let us know how the appointment goes. Do a google search for the conditiona dn research it would be what I would do. And remember we are here for you to cry to and lean on! I've had my share of diagnoses...so I can def. be a listening ear.
