Growing up the daughter of a rock star did not shield Kelly Osbourne from painful bullying. In her memoir, There Is No (Expletive) Secret, on sale Tuesday, the Project Runway Junior judge writes that she was a target "at every stage of my life," recounting times when "a grown man" lodged a bottle at her and she overheard someone say, "If I were (her mom Sharon Osbourne), I would have prayed for Kelly to be stillborn."

In an exclusive excerpt from the book to be published by G. P. Putnam's Sons, the 32-year-old author discusses numerous forms of bullying and its dire consequences.

Chapter 16: Dear Bullying

As adults, the workplace becomes our high school. We are forced to spend time with the same people over and over again, regardless of whether we like them. That new girl, the one who was hired for the promotion you didn’t get? Well, leaving her sitting at her desk alone eating a sad desk salad while the rest of you go out for lunch is bullying by exclusion. Consistently talking over someone in meetings, stealing their ideas, and trying to make them look bad in front of your colleagues or boss is bullying. So is trying to make sure the people who work for you feel worthless so they’ll never feel confident enough to ask for what they deserve or get a job somewhere that doesn’t treat them like (expletive).

The same goes for social media. People like to think that writing mean comments on a celebrity’s Instagram isn’t bullying, but no—it’s still bullying! People don’t understand the power of social media and the fires they fuel with their hateful comments. What we say and do online has consequences in real life.

Have you read the news lately? There have been an astonishing number of reports from all over the world about people who commit suicide after being bullied on social media. That does not even take into consideration the situations that go unreported or in which no one was brave enough to step forward and tell the truth. Bullying always comes back to how the bullies feels about themselves. If you’re happy with your life, you won’t ever feel the need to go out of your way to try to make someone else feel (expletive) about theirs.

If you are the victim of bullying, you just have to keep moving forward, and you’ll see that the biggest people in your pond are really just plankton in the oceanic scheme of things. It is a cliché, but a true cliché. The nerd who got picked on for four years in high school could easily be the next Mark Zuckerberg of the world. And the pretty cheerleader everyone put on a pedestal could end up alone, without any love or magic in her life, filled with regret as she looks back and realizes she should have been nicer. Once you learn what really matters, nine times out of ten it is too late.

Something that people always told me, which I really only began to understand recently, is that things really do get better. I say better, not easier, because life only gets harder. It’s just that you learn to live life to the fullest in spite of this. Bullies will never go away—it’s just that we have built the skills and have the power to become more immune to them. If you build your life on positive things, like hard work, love, and trying to be a better person, you can only grow. If you build your life on tearing other people down, you’re only going to shrink. I know what I want. Which one do you want?

Love,

Kelly O
