Call your PCP if you have a current script for them she should be able to prescribe you a 3 day supply until you can see a psychiatrist. Mine has done that for me once. He/She’ll also be able to recommend you to a psychiatrist if you need one. If it’s an emergency go to the ER, benzo withdrawals are not fun, been there done that. But if you aren’t on a script at all no one is just going to give out benzodiazepines.
