The good thing is that although it might feel it in extreme anxiety, anxiety will not cause you significant harm. Use some skills. They work faster than a pill, especially one that you will have to wait hours and hours for. If you are of age have a small glass of wine. Way cheaper than a trip to the er with quicker results. If you can try to get into a dbt class. The module on distress tolerance will be very useful for a whole bunch of things.

Best of luck for you!
