ER's in general are really skittish about psych meds and of course benzo's of any kind.

Only advice I can say is if at all possible go plant yourself in your new Pdocs office, Might take a few days.. But in general there is always going to be a no show or eventually someone will realize that you do indeed need help NOW and they will squeeze you in. If you have taken meds before and have bottles take those with you, Also try to get a copy of your medical records to have in hand from your old Pdoc.

Im sorry your struggling so much.. Squeaky wheels do tend to get the oil and spending the day in the waiting room usually gets a quick spritz of oil.
