It's late Sunday night and I've got to get to bed so I can get up for work in the morning.  It seems like there is no real weekend anymore.  I'm so tired by the time it comes and then I rush to get everything done that Dad needs and all the laundry and cooking for the week.  It's over and I'm as exhausted as I was when it started.  Every once in a while there is a little part of me that feels resentment that there is no "me" time and I feel guilty for that.  Then I think about how completely empty life will seem when Dad's gone and there will be so much time that I will be overwhelmed by it.  As the years have gone by it has come to feel that my purpose in life has been to take care of Mom and Dad.  When they're no longer here...what is my purpose?
