my adopted family commited Treason against me

I still think my adopted family committed Treason Against Me by Betraying me and using me so they could have a child but i'm about ready to change my last name a middle name the family name of my birth mother and father and denounce the family name of my adopted family
I don't want to Carry the Family Name of My Traitorous Adopted Family Any Longer I Am Ready To File The Paper Work And Go Back To My Roots And Carry My Real Family Name Of MY BIRTH FAMILY The Name I should Have Been Given AT BIRTH
