Can You Receive Anointing of the Sick Multiple Times?

A listener named Carol asks Father Dave about the Sacrament of Anointing of the Sick. She says, "As someone with an autoimmune disease called lupus, every couple of months when the Anointing of the Sick is offered after Mass, I go up for the anointing. Am I abusing the Sacrament by doing this because I'm not critically ill?"
