Angelic Advice

Dear Shay, I really enjoyed your site. I had an angelic experience a few years ago and it was almost like a miraculous healing from chronic fatigue. I learned that the angel of healing is Raphael. At the same time I have a great attraction towards St. Michael because I have always feared the forces of evil and I feel that he protects me. Can you have more than one guardian angel, and if so, how can I improve my perception of them?
