Dear, Welcome to HCM We understand your concerns I went through your details. Clinical depressive disorder is a neuro-chemical disorder. The Main Causes of Depression ranges from genetics, loss of loved one, grief, obsession to serious illness and substance abuse. There are many researchers who believe that an imbalance in serotonin levels may influence mood in a way that leads to depression. Anxiety and PTSD could be clubbed with your depressive disorder. Clinical depression is usually treated with a combination of psychiatric medicines, psychotherapy, life style changes, meditation and exercise. These therapy methods are highly personalized methods and therefore only an expert will be able to help. Once you make the necessary amendments in your life with the help of the above said therapies and life style changes, learn how to manage the depressive episodes without medicines and learn to relax, the medicines can be weaned off over a period of one year.
