Suicide is caused by long-term depression sometimes situations that seems to never pass a lot of foolishness at times. I've known a couple who drank poision because of financial problems. I've known a mother who killed her two kids then took her own life as a result of husband being unfaithful and who abused her continuously. Most times it's an emotional factor and at times it's out of frustration. When a person reaches a point where they feel helpless, like there's no other way out of a problem, no one to turn to for advice or to even talk and shed light on a situation suicide is the only thing they ever think about at the spur of the moment. It's really sad and heartbreaking.
