My Missing Piece

a girl is getting abused.
she's adopted but her parents are lovely.
she doesnt know her real last name, she only knows her first name which apparently her birth mother insisted on her keeping.
she has so many built up feelings that she doesnt know what to do with.
her relationship is abusive which means she has a lot of issues that she needs to work through.
she wants to play football professionally but can't seem to get scouted to play. it's also the only thing keeping her around.
she knows nothing about her birth mother so there's no point in her trying to find her.
