Managing intense mood swings
Mood swings are one of the psychological symptoms of fibromyalgia, and this may be worse when a person first learns about the disease. As noted, grief and anger are normal reactions when diagnosed with a medical condition. But in the case of a pathophysiologic disorder like fibromyalgia, the effects of these emotions can cause a bigger pain to the patient. As the depressive episodes start, the pain gets worse.
This is why better management of your emotions may help in reducing the pain. Of course, depression is a medically diagnosed disorder that needs proper treatment, so consult your psychiatrist about taking any drug. Furthermore, simple steps of managing your response to your medical condition could be trained, but it does take practice and patience.
