I feel bad but do I need to make myself miserable for the rest of high school, to make her happy???????? “
Is it really such an either/or situation? Does making her happy HAVE to make you miserable? You don’t have to be her best friend (really), but you should not put her in cherem, either. You would not like it if the clique of friends you belong to suddenly decided YOU were persona non grata for some dumb reason (like they don’t like what you are wearing).
