One question which always comes to mind whenever anyone takes action, is why. I believe the why is very important and leads to the how. With both one can have completely understanding of the situation, even if you're the victim or the onlooker seeking answers to defuse a situation.
I've some theories I wish to share with the community, i'd love to hear everyone's thoughts.
I believe not all victims seek help due to empathy with their aggressor, it's possible even fear of retaliation is a factor. Is it possible that bullying can come from even those we love? I believe it's possible those we love are the ones we let, hurt us the most. Have you ever noticed how difficult it is to say "no" to friends? Imagine how many times your friends ask you for a favor, chances are you want to help your friends and are capable, so you do. Sometimes even at greater cost to ourselves do we help our friends and not say "no". It's important to know when and how to say no, no matter whom it is. Imagine how difficult it'd be to say no to a complete stranger, for example homeless people. In theory let's say homeless people are bullies of emotions, and they know how to receive our empathy in their own ways in order to get what they want and achieve their own goals. Well, remember saying no is important and so is helping others, but there's a point in which helping others becomes an abuse to oneself. If I lined up 10 homeless people and you have enough food/money to assist 3 homeless people would you? What about the 4th who saw you giving the the first 3 and so forth? Well the moment you give it's your responsibility to say no when you can no longer give. Once you've said no, know it took strength and courage to say no to someone in need when you yourself couldn't give anymore. Bullies take power and refuse to give it back, make sure you say no to bullies who try to take your power, your courage, and your strength.
