Toxic friends

(!Gore and horror...and maybe smut lol!)
When Mary was young she was cursed with seven spirits in her head that could take control whenever they wanted. They ended up becoming basically her siblings and usually they all make sure everyone else is just fine with them taking control.
Mary finds herself with a few toxic friends, and somehow doesnt know yet. Eventually they get sick and tired of her and decide to get rid off her. So what do they do? Tie her too a tree in a haunted forest...then proceed to die lol

Mary as well as the other seven are my fursonas lol-
