Clinical depression is the most prevalent mental illness in the USA today.
Seventy percent of the time it can be treated with a combination of medication and psychotherapy. Depression like a physical illness needs treatment or it gets worse. It often runs in families. Some people express their depression somatically and go from doctor to doctor with minor or major complaints such as gastritis, stomach pain, back pain, fatigue and anxiety. Depression can be so serious that its sufferers cannot get out of bed to get on with daily activities.
