The hardest thing in life is losing someone that is close to you it changes the way you act and live your everyday life. Every second you are thinking it can all be taken away from you because you have had that feeling before.  It also changes the way you think you start to do the things that you enjoy and stop worrying about what others around you will think.  Losing someone is a life changing experience because it shows you what is really important you start to focus on the big picture and not the little things in life.
