On the one hand, if Essie hadn't written that letter - the one that only her best friend was meant to see - then she'd still be living like an actual proper grown-up, tucked up with Paul in his picture-perfect cottage, maybe even planning their wedding. On the other hand (if her true feelings hadn't accidentally taken the Internet by storm, that is) she never would have met Zillah and Conor - not to mention Lucas. And she'd never have found out just how much life there is to be lived.
