Carey is an active Episcopalian. She stated in 2006: "I do believe that I have been born again in a lot of ways. I think what I've changed are my priorities and my relationships with God. I feel the difference when I don't have my private moments to pray. ... I'm a fighter, but I learned that I'm not in charge. Whatever God wants to happen is what's going to happen. I feel like I've had endless second, third, fourth, fifth and sixth chances. It's by the grace of God I'm still here." In April 2018, Carey opened up about her struggle with bipolar II disorder. She, self-reportedly, was diagnosed in 2001, but kept the diagnosis private. Recently, she has sought out treatment in the form of medication and therapy.
