Committing suicide takes incredible bravery, I don't care how much people say it's a sign of weakness. All living beings have an inherent fear of death and no matter how awful life may be, it's not easy to take one's own life.
Nonsense. The reason people kill themselves is they believe it's preferable to facing something else. So yes, it IS a sign of weakness, unless, of course, that something else truly IS worse. Continual, debilitating pain which can't be treated or cured, for example. Or some terrible physical impairment.
One of my uncles killed himself when he got a girl pregnant outside of marriage back in the 50s. I regard that as weakness and cowardice. He couldn't face his family.
