I've been reading this thread with great curiousity. Although I know your not looking for people to believe you, but I'm sure you can understand how difficult it is when the end of the world has supposed to have happened (from predictions/visions hundreds of times in the the past?!
I'd really love for you to explain in more detail what makes you so sure? What feeling go with your experiences and what would you advise others to do in preperation/awareness for the near future?
