I also have GAD and worry about things. I finally had to pretend to be an ostrich and "stick my head in the sand", so to speak. I know avoidance isn't the ultimate solution, but it works very well for me.
I am not allowed to watch any news, nor am I allowed to read the newspaper. I get news from *****, and from stories that my husband will filter to me.
The oil spill in the gulf, and the nuclear reactor damage in Japan both sent me into a tailspin. After that, I have gone news free......
I truly believe that advances in communication have contributed to the increase in people diagnosed with anxiety. In the old days, before TV and internet, people knew only what happened in their immediate area. News was who was having a baby, or who had died, or who had the best garden. No one knew what was happening in the rest of the world. News for even major events like wars, trickled down to people over weeks and even months.
Now, we are "bombarded" by everything that's happening everywhere! Wars, pandemics, earthquakes, tornadoes......is there any wonder so many of us suffer from anxiety when confronted with information overload?
Anyway, try limiting your news intake. Watch only TV that makes you happy. Read only things that you enjoy. When someone starts talking about events that trigger you....step away. My family helps me by not talking about issues that will trigger me at the dinner table.
I realize that this is a type of avoidance, but my life is better, my outlook is positive, and I'm not "stewing" in doom and gloom. So, for me, it helps tremendously.
I also took Lexapro for several months to help me break the "worry" cycle. It also helped tremendously, and during that period, I searched for...and found, strategies to help me deal with my anxiety.
Good luck to you!
