OMG ~ Your previous doc should have given you enough until you got a new doc. This is unacceptable!!! This can be dangerous.
You might try the ER - they might give you some, but I highly doubt it.
Take some Benadryl - it will help with the withdrawals. You might have to tke 2 to make you feel the effects. Make sure you drink PLENTY of liquids with nutrients in it, like Gatorade or something. But drink LOTS of liquids. The sooner you can get this stuff out of your system, the better.
The Benadryl won't hurt you. It will just calm the effects of the other stuff.
Best of luck and God bless. Please keep us posted, ok?? Hugs, Lee
