Holly Willoughby may be a cool TV chick, but things were very different when she was a teen...

We asked Holly what advice she would have given herself as a teen. Here's what she had to say about heartbreak and letting go

Dear Holly,
I just want to tell you to stop obsessing about your boyfriend. After three and a half years together, he’s moved away to uni and you’re terrified he’ll meet someone new. Don’t let that fear take over your life.

It’s hard, because he’s your first love. When you started dating, everyone at your all-girls school was really jealous of your blue-eyed rugby player boyfriend. It made you feel really special when he’d turn up at the school gates and kiss you in front of everyone.

He made you feel secure, and taught you that a good relationship is about trust. Now, though, you’re forgetting it. Because he’s two years older, you’re worried he’ll get someone more mature.

Your fears are taking over your life. One night he promised to call you before 10pm, but you didn’t hear from him until the next day. You spent the whole night crying, imagining him with another girl. You think about him constantly.

But you need to let go, for your own sanity. I know you don’t like change – you’ve got the same group of friends you’ve had since you were five because it makes you feel safe. But you can see your jealousy is making him pull away.

When he ends it with you after he starts uni, because you were too clingy, you’ll discover the change is actually good. It means you have to take risks: meet new people and do new things. You’ll move to London… and the singledom will lead to incredible opportunities.
