Depression in this particular age of your daughter is mostly due to social and interpersonal relationship related stressors, and due to poor coping abilities of individuals to deal with those. Very common and very curable, if properly managed. However, a proper assessment of severity of symptoms can only be done by through history and examination that warrants in personal presence of a psychiatrist, for which a psychiatric consultation is highly advisable here. A psychotherapy sessions and A course of antidepressants like Escitalopram can be considered.
