Then you should also know that the people in your circle of life are your responsibility, and that a suicide is just as much your failure than it is the one that has committed the act. I firmly believe that.
Sad and tragic. If you have a friend or family that commits suicide IT IS YOUR FAULT IMO. There are too many resources for this to be able to happen. Just educate yourself and learn to read the warning signs. The moment leading up to act act of suicide is a slow burn. It is 100% preventable if family or close friends intervene.
