Hi Julie,
Welcome to our community. First you do have to get the statistics out of your head. Just like David said its just an average. Did you read Davids signature, now theres a survivor, along with many on these boards. The early stages of dx are very difficult, you are so overwhelmed with fear that it seems to take over. Finding these boards has been what is getting me through this monsterious illness. Just being able to talk to people who really get it, cause trust me you will come across some who dont, but thats another story. I am sure its not easy leaving your family either. Eventually you will cope a little better, its not so much that it gets easier, its just you learn how to live with it. I know you will find a lot of support and information here. Welcome Julie
