You can get through this. I know you are aware of the difficulty with the first few days. If anything, you can make it through this and be stronger for it without the use of meds. However, if you really feel that this will not work without meds, then the emergency room is an option. I dealt with anxiety for years, still do on occasion, so I understand the dynamic here.
I do understand why the doctor would want to see you. She is following the laws that are in place. If you do have another doctor that may help you please let the first doctor know that you have been helped by another professional. Keep posting and reading.
