Bella, have you read Fibro 101 yet? If not, I suggest you do so you can learn all about this illness. Fibro 101 is the first thread on the forum. Good starting links would be Symptoms, What Else Could It Be, and A Thorough Explanation of Fibromyalgia. You just might see yourself there.
No, this is a true illness. It is recognized by the American Medical Association, the American College of Rheumatology, the National Institutes of Health, and the World Health Organization...just to name a few. It's a painful, tiring illness and those with this illness are very often misjudged since we look just fine.
