Just because people commit suicide, doesn't mean that they are weak, it just means they are sick of everything that has happened in their life and they don't want anything else to happen. It is why people self-harm.
They are cowards. They are weak they can't face the difficulties n challenges of life. Life is never gonna be easy but it doesn't mean we opt for ending it through suicide. Life is a precious gift of god. But wasting it by fearing from challenges is foolishness.
