after death

exactly one week ago, I had fallen and hit my head rather hard. the trauma was severe enough for me to lose consciousness, stop breathing, and my heart stopped. i was dead by the time the paramedics arrived.
Although they were able to bring me back, I believe that part of me is still in the land of the dead. I, am no longer alive, but living dead.

Granted, I have all functions of a living organism, yet my soul is now incomplete. there is a large part of me, or the fabric that makes me who I am, that is lost in shadow.
i just needed to get this out of my head.
if anyone has anything to offer, please do.
