If I could go back.

I was thinking what if you could stop time or you could go back and change something you did worng or something you didnt want to do. would you do or would you leave it the way it was??? sometimes I wish I could back even if it was yesterday because thats the day someone you loved got hurt or maybe you got hurt maybe you just want to relive that moment. I know there is a few day I would go back too. What if you new you were going to die in a few months would you go out and do stuff you always wanted to do??? or would you just cry because you were going to die??? What if love someone but they have to leave or you love they but they dont love you back?? would you try to go back and fix what ever was wrong?? I know a lot of poeple that would love to change things that happened but you just cant. I would go back in time and stop poeple from leaveing or stop them from doing worng things. I pray to GOD every night that those people would come back or for Him to take me back in times so I can stop them but it will never happen because GOd makes those things happen for a good reason or maybe he just wanted to open there eyes I know if I could go back to just a few day ago I would but just to help my brother because he needed it and because I love my brother so much.
