Waterford — Three teen sisters here are trying to make people facing illness feel like royalty. Taylor, Kayla and Emily Roy, 17, 15 and 14, respectively, have been collaborating on a project to make and distribute tiaras to people who are battling all types of illness. “Our mission is for the tiaras to promote confidence when dealing with medical providers or feeling icky or getting treatment,” Taylor said. “They’re also a reminder that you’re a warrior, you’re a princess, or prince, and you remember to practice acts of self-care and to treat yourself gently.” The idea was influenced by personal experience. The Roy sisters’ mother, Natasha Roy, has a rare blood cancer called Polycythemia Vera. While battling the cancer, Natasha connected with others in similar situations via Facebook. A woman contacted her about “Tiara Tuesdays,” named as such since that was the day Natasha received injections for her cancer.
