Singer/songwriter Amy Grant, 52, is a six-time Grammy winner. She also one of 42 million Americans who act as caregivers for loved ones. On Friday, Grant spoke with Katie Couric on "Katie" to talk about the most meaningful tour of her life -- in 2008, when she came back from the road and decided to take a break from her career to care for her mother, who died last year. Now she is caring for her father, a retired radiation oncologist, who suffers with dementia.

Caregiving "can be such a lonely process, but I have learned so much from people who have open up to me about their experience so I just thought I want to open up the dialogue; and also my sisters and I all went, 'what have we planed for when we're old?'" Grant said.

  • Let The Person Speak

    When an ill person brings up subjects that make you feel uncomfortable, it's natural to want to squelch the discussion or rapidly change the subject. However, it's very important to listen unselfishly and avoid responding with, for example: "Let's not get into that right now. Can't we discuss something more pleasant?" or "Do you really think it's helpful to dwell on this topic?"

  • Know When To Say "I Don't Know"

    Whether the patient asks a spiritual or theological question that catches you off guard or she wants to know about the side effects of a medication, it helps to learn how to be noncommittal without seeming evasive. You don't want her to think that you don't care or that you're hiding something, and you definitely don't want to offer misinformation that might do more harm than good.

  • Don't Hesitate To Call In Spiritual Help

    Even for people who weren't very spiritual or religious throughout most of their lives, it's natural to experience spiritual anxiety during a serious illness. And it's also natural for this anxiety to lead to questions that caregivers might find difficult or even overwhelming. If your loved one asks, for instance, 'What's next? Will prayer help? Why did God let this happen to me?' it's best to call in a qualified cleric.

  • Let The Tears Flow (The Patient's And Yours, Too)

    Just as most of us are not comfortable with chronic illness, we are also not comfortable with crying. When tears appear, we tend to whip out a tissue and murmur something along the lines of, "It's okay. Don't cry." From now on, continue to pass the tissue when your ill loved one starts to tear up, but don't pressure him to stop sobbing. Tears are a natural emotional release for emotions ranging from anger to sadness to fear, and can be very therapeutic.

  • Resist The Urge To Spout Platitudes

    When your loved one is uncomfortable, upset, or worried, you might be tempted to utter platitudes like, "Everything will be okay," "I know how you feel," "God has given you a long life," or "It's God's will." While we hope that these phrases will be a quick fix to problems we'd rather not deal with, the truth is that they're trite and meaningless. What's more, sugarcoating reality doesn't fool most people, and it certainly doesn't spark positive change.

  • Respond Constructively To Anger

    Anger is a natural human emotion, and it's important to recognize that chronically ill people have a lot to potentially feel upset about. Understandably, many patients are angry that they are so sick. Plus, their pain and energy levels might make them less patient or less able to handle stressful situations. Therefore, it's not unusual for caregivers to be on the receiving end when their loved one's fuse blows for any reason.

  • Seek To Connect Heart To Heart

    Understanding how and why an illness is getting worse and more painful is intellectual. But experiencing it is a very visceral and emotional thing. The patient needs for you to connect with him on a heart-to-heart, gut-to-gut level, not just a mental one.
