realising that i am not you and therefore have no idea who you address in this piece my comment wont seem very useful at all.
when i read the formed from clay thing i couldnt help but think of the creation story and how god formed man from clay
then the second line suggests to me that someone other than the creator has shaped you... has carved you into the person you currently are...
that could be a parent or a lover or another figure who has some kind of authority over you as a person
these indentations/scars make me wonder how literal they are to be taken...
in my life indentations and scars are more memories and reminiscings than actually visible scars physically located on my body
but it is true that scars cause us to view the world in a new way and create the way we percieve things.
sometimes i think we need to come to the place you have come to at the end of this piece. in saying you are who youve been made to be but not who you want to be opens up the opportunity for you to persue what it is you want to be in a fuller way.
while the ending should leave the reader with a sense of gloom or forboding i am left with a glimmer of hope... if you know who/what you dont want to be then maybe you have half an idea what/who you do want to be and maybe you are able to start gradually working toward becoming that person.
