Labelling suicide as selfish is just lazy thinking. Every individual suicide has a multitude of reasons behind it, and when a society perpetuates an attitude of ''Sucide is selfish, mental illness is weird'', then yes, people who are depressed are going to think ''Why bother discussing my suicidal feelings with anyone? They'll either label me as ill or selfish''. Then the living wonder why victims of suicide didn't talk about it when they were alive.
