How to break with bipolar suicide Bride?
My friends friend is very depressed and suicidal during the relationship appears. We have made an investigation and found that people with bipolar disorder are 30% more likely to commit suicide risk of a rupture. His parents did not receive their medicine, or take it to a doctor, because her mother died of some drugs, as was also bipolar, probably among other things. His parents think that all doctors 're crazy. She is very paranoid and my friend feels trapped in the relationship. He really did not want to be in it, but he is afraid for her and what it could do with him even. She watches a TV show called "taken" a lot where people kill their ex after breaking with. My friend does not want anything to happen her or him .. And their parents can not do anything. He is only 15, as am I, and we are sure he would not want to contact the authorities or the hospital. By Please help my friend break the relationship, without hurting .. Thank you.
He is only 15? It's not his problem as an adult to control almost none of this. Breaking hurts no matter what he does, and nobody can avoid that. I would advise do you have to do to stop it and if you see signs that it may be harmful itself, whether to call their parents or the authorities (whether Child Protective Services or 911). At 15, his options are limited and his power over her is zero.
