Well, I had no problem getting a doctor's note from the clinic. I just called the nurse, told her that my ex-doctor (I have an ARNP now that only comes in to the clinic one day a month!) had told me that if I ever got a summons she would give me a letter. The nurse wrote the letter and got one of the docs on staff to sign it. I picked it up and sent it to the court clerk and I'm excused! YAY! And if I have to do this again and again, so be it!
Thanks for eveyone's support!
