①About 43.5 million Americans are taking care of aging relatives and friends, sacrificing(牺牲) time, money and sometimes their careers and personal health. They are doing the work of professional caregivers, who spend years training for the job. As baby boomers age, the demand for unpaid caregivers is rising. Meanwhile ,the number of them is dropping rapidly thanks to smaller family sizes, higher divorce rates and increasingly demanding jobs. This November, actor Rob Lowe offered to tell his story and send some encouragement to the millions struggling to care for a loved one.

②I had my first experience with unpaid care giving fairly early. My father, Charles, was diagnosed(诊断)with lymphoma at age 50.I was 26.Luckily,he was financially successful and had a loving wife, my stepmother. It was challenging, but she was there from taking care of my father.

③In my late 30s, my mother, Barbara Hepler, was diagnosed with stage 4 breast cancer. That was when I was introduced to the front lines of what so many millions are experiencing. She did not have a husband or a significant other, so it fell to me and my two brothers to handle everything from her initial diagnosis to doctor shopping, treatment options, driving her to appointments and, finally, the end of life-which was profoundly difficult, obviously.

④At the time, I was starring in and producing a network television show, The Lyon’s Den. It was fighting for its ratings life. If I took time off, the show would be canceled, I was responsible for 150 crew members ,so I had to find a way to do both.

⑤Besides. there is the negotiation of medical coverage, which requires phone calls, weeding through paperwork and talking to insurance companies and doctors. I remember thinking, Jesus Christ, if I were sick and had to do this on my own? I don’t think I could get out of bed in the morning.

⑥The people we are talking about-the friends and family members who are out there doing important work-are unpaid. Watching a loved one go through an illness, possibly ending in death, is stressful and depressing. Add economic and scheduling burdens, and the load for caregivers is heavy. To them I say, Don't forget about yourself. When you get on an airplane, the crew says, Secure your own mask first before helping others.”Why? Because without you taking care of yourself, you can’t take care of anybody else. That’s why I’ve partnered with EMD Serono andEmbracingCarers.com, where you’ll find invaluable information regarding everything you’ll be, or are, going through.
