online therapy for depression, Depression means different things to different people. Depression can be a symptom (as when a person says, ‘I feel depressed’), a sign (when someone observes, ‘he looks depressed’), or a diagnosable disorder. When we diagnose depression, we mean a disorder of sufficient length, with specific symptoms and signs, that substantially interferes with a person’s functioning or that causes great personal distress or both, It is important to separate depressive disorders from everyday ‘blues ‘or sadness, which are not depression. People with the blues or normal grief may experience short lived symptoms of depression but usually continue to function almost normally and soon recover without treatment.
