Im having severe physical anxiety symptoms because of my upcoming jury duty. is there a way i could get a doctors note to excuse me from jury duty? its affecting my well being?

Yes, that should be practical. Call your Jury office and ask if they would excuse you without a note from a doctor. If that does not work you can ask your doctor for a note addressed to the Jury office. Do consult a doctor any way as your issue is treatable. Wish you good health!

The best would be to talk to your doc who has previous documentation and can assess your anxiety in person. Strong evidence will be needed in order to obtain such documents.
