Hi, I'm new as well, I am going through the exact same thing right now, because of having enoumous amounts of stress on my shoulders. I have been missing work on and off and going for bloodtests and ultrasounds, because I am convinced that something is very wrong. Although I might actually be sick from something, because my last bloodstest showed a high white count which means an infection somewhere, or it could have been just from stress. who knows? but anyways, this has happened to me about 4 years ago and i eventually got over it and I had the help from this book I read which I recommend to everyone! It helped me out sooooo much, that i'm reading it again now. It's called, "how to stop worrying and start living" by Dale Carnegie. You can pick it up at Chapters. You have to allow yourself to worry for only short periods in the day, then the rest of it use for something good, like exercise or a hobby, anything but allowing yourself to worry. It's hard, but it can be done and well worth it, that's for sure. It's good to hear others problems on here, because right now I feel like I'm the only one going through all this stuff.
