I went to a lecture once (not sure if it's the right word here but bear with me) held by a father, his wife and their two daughters who where the founders of a anti-bullying organisation called "dare be yourself". Their younges daugther hanged herself after beeing bullied, and they put a lot of effort into helping people realise what bullying is and how to deal with it from a emotional perspective to help young students.
This girl had help, from techers, but they did too little, i.e they said "now children, apologize to eachother".
She had help from family, but eventually the bullying outweighted the support.
She told the bullies to leave her alone after they started to slander her with words like whore and similar, at wich point they beat her up.
She was supported by a member of "Friends", an anti bullying group that sends out representatives to help bully victims. This representative then cornered her in a bathroom and sexually assulted her.
My point is, getting help is sometimes not enough, standing up is sometimes not enough, and sometimes you can't even trust the people who are there to help you. To say that you need to "deal with it", "man up" or similar comments is not just disrespectful, it's also one of the worst things you can say to someone who's already in a position where they feel like the world is against them.
One main problem, in my opinion, is that teachers are not taught how to handle situations like this. Someone made a comment about how they are afraid of getting sued or fired, well that's not how it works! A teacher is expected, even supposed to help a bully victim, but the truth is that teachers are just as vulnerable to bullying as the students.
I wish this was a swedish forum, then I could suggest that you'd see "Henrik is a dork", a play/lecture where Henrik tells the audience about his childhood and the bullying he endured and how he got through it. I wish people could see it, it really points towards bullies and says "there, right there, is the problem and what it causes" as well as giving those who have been through it a sense of familiarity and hope.
