[/INST] Hi, thanks for writing. I have understood your concerns.frequent mood swings can be a part of bipolar disorder [mania and depression], reaction to stress, personality problem [borderline personality disorder].usually bipolar mania patient do not have insight for their illness. So you must be suffering from bipolar depression but you shut go for your personality evaluation also because frequent and rapid mood changes with tendency to harm oneself is more going towards personality issues.mood swings reactive to life events is also a different kind of depression.you will get all your answers when you consult a psychiatrist.treatment is different according to diagnosis for which you have to visit a doctor.I think this info will be helpful to you.best of luck. </s>
