Hi, Big Bird, and welcome to the fibromyalgia forum! There is nothing to be frightened about. Yes, you can have pain and fatigue with fibromyalgia but you don't die from it. You will learn how to control the pain and still have an enjoyable life. I know I have and I've had fibro for 21 years.
The fear will cause anxiety and depression which, in turn, will make the pain worse. So, what you need to do is arm yourself with knowledge about fibromyalgia. You have come to a great place for that! We have wonderful members on here that have great ideas to help you learn how to live a full and enjoyable life with fibro. AND, a big plus is we all REALLY do care about each other.
As Missy said, start out with reading the Fibro 101 thread. There is a heap of information in there. Also, back posts have a world of information in them, too. Don't hesitate to ask questions, either. We are here to help you. I'm sure you will have more questions as you start to read about fibro. Meanwhile, I'm so glad you joined us and I hope to hear more from you soon!
