Age, sex discrimination in Nursing

I am a 64 year old, male nurse. I graduated with honors from a top university nursing program, am certified in my specialty (oncology) and have more than ten years of inpatient and infusion clinic experience. I have been seeking work for nearly two years. I have been in Florida for the past year and have not even been able to find a volunteer position. I fear I will never be employed again.
Hospitals have acknowledged hiring new grads, but treat me like a leper.
When I ask folks at my church if they could help me network they decide to avoid me. I have been told that if I had the background I claim and can't get a job, I must be a criminal or a drug addict. This is hurtful. Any comments?
