A girl is going out camping in the woods with her best friend. As time goes past he becomes different (skin becomes paler, behavior changes either to apathetic and numb or brash) and from information and/or mysterious beings sighted in the woods, she suspects that he's been replaced by a monster. The story ends without any conclusion, just that she's terrified and is desperately begging for anyone to help because neither he nor life are the same anymore (perhaps while she prepares to deal with the monster-friend?)

Sound familiar to anyone? I can't remember any specific wording to it, just this.
