Like others have stated, do not take it personal, and move on, most likely this person is not happy and all her freinds know her well. I have gained many stellar patients by letting go patients that made life hard for my staff and myself. My other patients had respect for me to not allow a bad appple to ruin the whole crop. I am sure her friends take her with a grain of salt and ignore most of her complaining. Most people understand Doctor's are pulled many directions these days. Good luck and continue to work hard for your pateints, they will appreciate you in the long run.
