serotonin is one of a few chemicals that may be low in depression but depression may be due to genetics stress and your personality or coping style. some of us think that psychotherapy actually exercises the front of the brain which helps to increase many of the chemicals that are low. so psychotherapy changes chemical levels too perhaps. if counseling has routinely helped you keep doing it. if it fails to help then a med may be called for. unfortunately i see that the more depression spells someone has then often they do end up on a med more often.
can antidepressants help get the serotonin in your brain back in sync?
