Is fms real or am I just depressed?

Real. Fibromyalgia has been shown to be a real entity with measurable changes of brain chemicals. These changes are not only related to the symptoms of fibromyalgia but also to those of depression. There is help. See your doctor.
Real. Fibromyalgia is not depression. However living with chronic pain can cause feelings of anxiety and depression, which can worsen the symptoms of fibromyalgia.
