Hello, Welcome to Health Care Magic There have been many problems in past like family dysfunction, emotional trauma which are the main reason for the symptoms of depression and stress. You have good family but still have problems of depression. The reason is most probably adjustment disorder with depression and not bipolar illness. I would advise you to consult a psychiatrist for opinion. Cognitive Therapy by a trained therapist will help to explore faulty cognition, unresolved conflicts and emotional trauma if any. Once the conflict is identified then treatment becomes easy. Medicines like Fluoxetine, Sertraline, Escitalopram etc are common antidepressants used in such cases. Consult a psychiatrist for evaluation. Thanks
