I’ve been taking xanax for 5 years?

I’ve been taking xanax for 5 years and it’s been 2mg and then 1mg my last script I picked up when I took the tablet nothing happened it just didn’t work as if I had taken air. I’ve read this happens but this drug has given me my life back and I need to know what to do to or is this the end of my great meds. It’s happened once before but just a few days and then normal. I need serious answers and help.
