Rhiannon, this is terrific news. Allow yourself to be happy & relieved. Ask not "why me?" Instead, say, "Why not me?" It is obvious that it is not your time, and you have much more to do in this life!
   Sometimes we often think that we are only one small person, and wonder if we'll ever accomplish anything of importance. We often never really know about the many people whose lives we have changed for the better by being a friend, sharing a song, giving a smile to a passerby, or listening to a complete stranger pour their heart out-which helps them to sort out their problems & decide which direction to go in their life. Never underestimate the importance of one human being.
