i hope this link will help you
Crazy, this got me so worked up because Dec 21, is my birthday. I was watching the news the other day where I seen they were offering "End of the World" cruise. I heard the guy on there saying how some people were going to be worried but everything was going to be fine!!
The same thing happened with many people in 2000. I have faith that everything is going to be alright. I hope you can too.
Don't think you're strange for having this fear. I would recommend counseling to help with coping skills. Would that be possible for you to do?
