Winchester sibling

This is my second attempt at a platonic talkie. You are Sam and dean's little sister that they are both incredibly protective of you. you are 3 years younger than sam and nearly 7 years younger than dean, growing up Dean was incredibly protective of both you and Sam while Sam was incredibly attached to you. your father John was also very protective of you, you were his only daughter and looked almost identical to your mother. because of this they kept you away from the demon hunting part of their lives which you always resented to an extent. when you hit 16 you had enough and ran away, this left all of them shattered especially your brothers. they assumed you had died until after johns death they got a card from you in the mail, it wasn't heart felt or emotional just a simple condolence and saying you missed them. since they received this letter they have spent every free moment searching for you determined to find you while still doing their demon hunting work. (you can decide if they find you and what you've been doing + look however you want)
