Writer's Block?

I've not written anything for a long time because everytime I sit down to write nothing comes out. I must have writer's block? I have many things to write about and now more than ever I appreciate people who can put their thoughts on paper so eloquently. Terry Tempest Williams and Annie Dillard come to mind and of course one of my all time favorite nature writers John Muir who paints his words like a masterpiece. It has been so crippling that my wife gave me two books to help me,
"Writing Your Life" by Lou Willet Stanek, and "The Legacy Guide" capturing the facts,memories, and Meaning of your life. by Carol Franco and Kent Lineback.
Maybe it's just the ageing process or the fact that the winter weather has dragged out so long without warm sunny days? I flew down to Santa Rosa the week before my mother's 92nd birthday because she was ill. I made certain that she went to see the doctor. Her symptoms lasted nearly a month before she finally after two kinds of antibiotics recovered. I can't blame her for not wanting to go to the doctor because as she say's "They never do much except look in my mouth. take my temperature, and listen to my heart and lungs". Going to the doctor can be dangerous for an old lady with a compromised immune system. Exposure to people who are sicker than you is always a "Crap shoot". By the way I'm convinced that flying from Portland to Santa Rosa on Horizon (Alaskan Airlines) is much more convenient than driving 11 hours. They also offer complimentary wine during the 1 1/2 hour flight. It is usually wine from a local winery. I recently discovered that when one clicks on a category of "Interests" listed in a blog you find many other blogs with the same interest as well as many, many other interests. It's like falling into the abyss of the "Black Hole" of cyberspace or as Forest Gump said "like a box of chocolates, you never know what you're going to get". Try it sometime you may never come out.
