My friend has some symptoms of depression, like she has always negative thoughts about herself, fear from exams so much that her mind goes blank and she submitted blank paper even after studying so much, sometimes she starts weeping even in the start of some competitive exams that she knows nothing, she keeps talking negatively about herself and remains sad, but not all through the day means 10 12 days in months she shows such kind of behaviour, yesterday she consulted a doctor who is a MD he suggested the medicine, oleanz 5, and said that she should consult him after 3 weeks, is the medicine right for her, as her depression level is not that much, she remains happy and shows these symptoms only few times in 3 or 4 days and I am also concerned about adverse effects of the Medicine on her, Please suggest the right advice for her, should she consult a counselor or the medicine given by that physician is right for her?
