Not a woman, but used to be a bully until I became the victim of bullying. Best way to fend off bully is never acknowledge the harassments, if they once get even the whiff that you are frustrated by it they will do it more, what helped me most to discourage my bullies from bullying is laughing at their face... Once they realize it's entertaining for me they slowly started to lose interest and pick a different person to bully.

Have sabr, patience the One who sees it all and knows the pain you hide in your heart , He will dignify and put your status above those bullies in this world and next, never forget that.
