It's 1989 and 15-year-old Rhea is a 5th former about to embark on her GCSEs – so of course she's going to be stressed.

And of course, it doesn't help that career's advice is coming up and her teacher is on at her to decide what she wants to do. She doesn't know.

And of course she looks unwell; she's been struggling to overcome this chest infection.

And of course it doesn't help that her mum won't let her stay at home and recover, as "it's a very important year… no missing school."

If it's such an important year, why is everyone on at her? Why can't they get off her case?

And so what if she's not eating? She's just not that hungry.

Growing up is getting all too real… but little does Rhea know that her reality is about to change forever.
