Regaining focus after losing a loved one to cancer is a tough thing for anyone. Last month Professional golfer Tiger Woods missed his first ever cut in a major championship at the US Open following the loss of his father Earl Woods to prostate cancer on May 3. Tiger regained his focus one month later to win the British Open today.

Mourning for someone you have cared for and loved is a necessary part of feeling better again and continuing with your own life. You will often experience emotions of intense sadness and despair, or it may be hard to believe that the person has really died. You may feel that crying is a sign of weakness, or that you are falling apart but grieving is the way we begin to heal ourselves, just as an injury needs time to heal.

With an emotional breakdown of tears on the finishing hole, Tiger Woods wept openly in the arms of his caddy Steve Williams. This was his first victory since his father's death and some critics questioned whether Woods could regain the focus needed to stay on top of the rankings in the professional golf world. Watching the British Open on television and seeing the final shot by Tiger filled my eyes with tears to know the pain this man felt while winning such a glorious title in golf without the presence of the father that has stood by him his whole career. But he regained his stance at the top of the world rankings and keeps the focus that was taught to him by his father Earl Woods.

"After the last putt, I realized my dad's never going to see this again, and I wish he could have seen this one last time," Woods said at the trophy presentation. "He was out there today keeping me calm. I had a very calm feeling the entire week, especially today."

Tiger Woods now has three British Open titles, the same as Jack Nicklaus, and his victory at Hoylake carried another comparison. The first major Nicklaus won after his father died in 1970 also was the British Open.

In the second part of the two-part exclusive interview with ABC's Good Morning America Diane Sawyer, Sheryl Crow shares she is cancer-free and feeling great as a breast cancer survivor. The diagnosis of breast cancer came as a surprise as she is not a smoker and has no family history of the disease. She received enormous support from her family and friends during treatment, whom she refers to as "this incredible tribe of women." Before Dana Reeve died of lung cancer, she gave Crow advice on dealing with the emotional aspects of being a newly-diagnosed cancer patient and dealing with the recent separation from Lance Armstrong by telling her that the only way to go through grief was to grieve.

Crow talked about meditating and changing her diet. "I kind of went into a full-on Eskimo diet, where I ate a lot of salmon. In fact, I'm salmoned out of my brains ... and really green vegetables, just eating really clean, organic food. Listen, I haven't had a doughnut in I can't remember when."

Breast cancer forced Crow into an introspective place of self-realization in facing and overcoming fears -- and the wisdom that comes with that when she said she tried to at least address her fears and not be overcome by them. "The fear of things not always working out. You come to a point in your life where you realize it's not my job to prove to my parents or to my record label or to the world or to my lover that I matter. The fact is that you matter."

"It's not a good place to be concerned with always being right with everybody, always pleasing people, because ultimately you wind up betraying yourself a lot."

Crow shared that she sees her breast cancer diagnosis and being a cancer survivor as part of life's deepening experiences where obstacles are removed and opportunities come in.

Last Friday night, Crow joined the Dave Matthews Band in a concert at Fenway Park. But before she went onstage -- in part of giving back as a cancer survivor --  she made an unannounced surprise visit to Boston's Dana-Farber Cancer Institute to visit children with cancer at the Jimmy Fund Clinic.
