i don't know who i am

I've been suffering with at least three different types of mental illness for the past eight years and i'm only 16, i really don't know what my personality is like because all of the traits i have that define me as a person are either traumatic responses or disordered behavior. They all say "you are not your trauma!" but all i know about me are broken pieces of the person i never had the chance to become, it's like someone killed me as a child before i could ever have the chance to become a person and now i'm just a bunch of broken pieces stuck together trying to survive and live a "normal" life but just failing over and over again
