May be. All required for her is to handle all those issues and have a clarity to lead a peaceful  and successful  life. Ask her to consult a Psychologist and express all her emotions which she underwent all alone. Sharing will help and also some of the guidance of the Counsellors will enable her to see from a different perspective. Very good my dear Friend.

Hi, from your description she definitely needs Psychiatric evaluation. This may be Dysthymia as opposed to Depression. Having said that however she will need personal evaluation by a Psychiatrist for a proper diagnosis. She may require medication for a short period, however she will benefit greatly from counseling or therapy especially given the fact that she had a rough childhood. Some of her patterns of behaviour like her fear of failure and mood fluctuations can easily be addressed by the therapy. She has to focus on her strengths. She has been a responsible girl handling so much. It just takes simple steps to understand that she need not give way to the stress she is experiencing. Please do not hesitate to seek professional help from a Psychiatrist. She can definitely get better. Hope this helps, All the Best!
