Saying Suicide is selfish amd cowardly is kind of ignorant. Can you imagine how low a person must be in order to contemplate taking their life? They are obviously not thinking rationally. Everyone always says never to make important decsions when you are depressed or traumatized and for good reason. I cant even imagine the low one must feel to actually follow through with suicide. I think some people feel as if they never fit in and are just living life on the outside and watching the rest of the world on the inside. Very sad, especially when kids do it.
I knew a guy through marriage who shot himself. He said he had nothing else to live for. He had lost his job and wife, so that and im sure some other things.
I also think some people are much more predisposed to depression, especially deep depression.
