If you can't get in to a dr soon, see if you can get a letter ( fax/email/letter) with some basic information and your dx from that dr that had the freak out , and go to urgent care or ER.

This is crazy, if she thought you should be in a hospital right away, and now you are having to wait so long for care.

I thought most dr offices leave a slot open for immediate care pts.

does the dr office that gave you the appt know it is for an urgent condition?
some places have a waiting list for when there is cancellations and will call to see if you are able to come in?? You can ask to be on that call list also.

But I really wouldn't wait at all- especially if it is getting worse.
