A shell of who I was

Growing old watching my mother grow old.  Totally new to me.  To all of us I imagine.  I watch my friends become grandparents, and I think where am I at?  I feel the same, yet different.  I know I am the same person, but yet not.  So strange to find a place in the world after your done with another place.  It's like we are shedding our skin.  Baby... shed..... child.... shed....teenager.... shed..... young adult, mother, care giver...... shed.... now what?  I feel like a locust.  the shell is the same, but where am I?
