Actually, I find it a pity that you have no education on mental health issues. Here... let me try to teach you something here. Suicide is often the result of a serious mental health issue, most often either Major Depressive Disorder, or a Major Depressive Episode inside another psychological disorder. When the individual is in this much pain, they perceive themselves as having a choice: either continue to be in pain or to end the pain. When someone is in this state, often feeling trapped, other options do not seem feasible. This is also why talking with someone can be a lifesaver. Unlike what you and some of our other folks who are minimally educated on mental health issues believe, this does not make the individual cowardly or weak-minded. The person is looking for options in, because of their mental health issues, they perceive as an untenable situation. It's an UNHEALTHY and harmful option, but with the state of mind they are in, it is the best option that ends the pain that they see.
There. You have now been given some basic information on this topic. I hope this helps you to not make these kinds of errors again.
