I am sorry that you become physically ill with your anxiety. I remember the 2000 scare to and we ate pizza and the world went on as the clock struck midnight. No computers crashed, the lights did not go out and I worked on New Year's Eve as if I could save the world.
I guess I am a bit of a believer in destiny in some of these things.........there is not much we can do to stop time so enjoy life to the fullest now.
Do not read the ENQUIRER unless you can laugh at the stories. Read a good entertaining book, much less distressing. Take care hun and keep posting. You have my support.
