Yes, there is a link between usage of birth control pills and development of depression. Oral contraceptives decrease the level of serotonin in the brain and can result in depression. But it seems likely that, in your case, the “other things going on in your life” may be more responsible for your depression than birth control pills. You can seek help from a support group, a mental health professional (psychologist), or friends and family to identify the possible emotional source of this condition. Coping may seem overwhelming, but you are not alone and there are tools that you can learn for dealing with depression.
