My daughter, 23 yr old, degree final year student has a love affair with a boy of a different cast and poor economic situations which is unacceptable at all to our family. We advised a lot in many ways but failed. We understand that the boy is not straight forward, having no true love but aiming at some other goals. When we insisted my daughter that this relation will no longer survive she threatened us of her suicide (even tried one day to cut her veins with a razor blade) or her departure forever somewhere and to earn her bread by selling herself. Now I understand/suspect that she is having some mental abnormalities rather than her love affair. She hates us parents and the one and only brother vey much. Sometimes she is found normal and sometimes found very violent. In this situation please let me have your guidance in order to get proper medication and treatment.
Degree understand your concerns went through your details. I suggest you not to worry much.  The mental pressure your daughter faced during the affair episode must have harmed her thought process. The resultant disappointment could have changed her thought process and overall perception. Suicidal tendency could also come out of depression which could be triggered by disappointment. Please consult a psychologist for counseling. If the symptoms persists even after three or four counseling sessions, psychiatric intervention could be required. Psychotherapy techniques should suit your requirement. If you require more of my help in this aspect, Please post a direct question to me in this URL. http
