How can you get rid of depression without taking drugs ?

Possible, but...: It's hard work. Many (but not all) people with depression can be helped if they did certain things irrespective of feeling down, depressed and unmotivated, including specifically, increasing their socialization, avoiding alcohol and substances of abuse and doing 30-45 minutes of aerobic exercise 5 days a week. When the depression is severe, avoiding antidepressants might be counterproductive.
