I would recommend trying to solve this situation by telling a proper administrator of the school so she can be disciplined properly. You could do a witches' bottle, but it would probably only cause her avoid you. Try to handle this without using magick. Write an anonymous note to an administrator.
Always do every thing you can in the mundane world first before hand. tell the right people, if not all the teachers and staff and warn them not to take it lightely because of revent events their should be zero tollerence.
and you choose to use magick i would recomend only using magick to protect your self. it shouldnt be used to affect others. what if some thought you where too nice and found that painful and anoying so they decide to work a spell on you? as well as your unaware of this persons situation and could be living in hell outside of school and doesnt know how to deal and a spell against this person make their life even worse...
Use personal defense and aid that you can get in life. A spell will not manipulate her physically or fully mentally, so you won't change her actions.
You can also inform the police about her actions which might be considered to criminal actions and offenses.
If it keeps happening you can curse her if you know how to. Now, I'm sure that people will keep jumping and saying that cursing is immoral and can backfire.
There is a reason they were made. People do not have to get harmed without giving a pay back. But remember that when it comes to curses and hexes the situation has to be critical, after you try to solve it by yourself and by the law.
Sometimes one needs to be Karma's little helper ;)
nicer to you, a honey jar spell. but you might have to tell if things get out of hand for everyone's sake. if it's who she is, or she's upset because of something, like home problems, casting to make her nice won't make it go away. just remember she's one person and she's being mean a bunch of people.
in the case of magic do a binding spell. take a pic of her and take a yarn. rap the yarn around the pic and say... i forgot what you say but look up the spell on here. i think it goes; i bind thee ___ or somethin. look it up. only in case of safe magyc.
In this case, I have to say it would be best to talk to a principal or administrator. If that does not work, I would try a protection spell (a simple one can be found by dragonfeather on YouTube).
The only reason I would discourage a binding spell us because you could end up binding your emotions to hers and you could feel just as angry as she does..
Be sure to research spells before you do them and know the reapercussions they could have :)
