I Am Not the Person I Used to Be

I Want The Old Me Back... I don't think I know Who I am any more somehow lost who I was I still look the same and sound the same but I'm not the same if that makes any sense. My purpose in life seems to have gone this just never happened over night I think it started years ago. Maybe it's just a part of life I don't know it's not that I don't like myself any more it's just I don't know were the fun loving person I used to be has gone I miss him and I want him back.
