See doctor: If depression is severe you need to be on a medication. Medications, counseling and exercise are the best treatments for depression. See your doctor and get to a counselor as soon as possible. Some doctors actually have counselors in their office, if not they can suggest one for you. If you feel suicidal or feel that you may hurt someone else please go to the emergency department immediately.

Your Dr can assess: for mood disorder & causative underlying medical conditions. Talking therapy (Cognitive Behavioral Therapy or insight oriented psychotherapy) is allows for lasting change. Psychiatric meds may be indicated. Don't isolate. Spend time w people. Use your support system. Get out. Get at least 8 hrs of sleep/ night & eat healthfully. Daily aerobic physical activity is a big +. Try acupuncture, tai chi
