'Things Will Get Better'

People say 'things will get better'. How do they know for certain? They are basing it in they're own lives. No one is the exact same, all people are individual. Maybe your life got better after some hard fall, but not all lives do. That is why there is suicide. An end to the pain of life, everlasting peace. Maybe not the correct route, but sometimes the easiest. Don't tell someone 'things will get better' unless you can be 100% sure.
