What drives a persons need to bully is actually feelings of personal inadequacy and shame that is then taken out on others in an effort to alleviate the pain, and feel just a bit better. However, as you may guess...the more I take my emotions out on others, the worse I feel about myself. So this becomes a self perpetuating cycle of abuse. To stop it, if you're "the person" doing the bullying, better outlets for alleviating YOUR pain, and effort to understand and work with your emotions will be required. If you're the person "being bullied"...you to struggle with feelings of inadequacy and shame, but just handle them differently. You shut down instead of get aggressive in an effort to feel a little bit better. Make it up its all your fault in your attempt to avoid conflict. You must learn to value yourself, and be willing to advocate for yourself as you take appropriate actions to keep yourself safe. Be mind full however, that in doing so, you don't become the bully.
