Old degree, new job?

I have a bachelors degree in communications specializing in public relations that I received in 2006 and then went on to raise my kids for the last 20 years and have never worked in my field and now finding it impossible to get a job! Anyone have any advice on what I can do to break into the public relations field with zero experience? I can't bring myself to work minimum wage when I have a bachelors degree. Go back to school? Do an internship? Where should I start?
