Crown was diagnosed with a rare physical disorder aged 12 and says being treated for the impact on her mental health has been really important.
The link between mental health and physical health is at the core of the Cambridge Children's Hospital vision.
Having a physical condition can have a big impact on how you feel psychologically, and vice versa.

She says having someone ask about her mental health would have given her the chance to open up.
Crown is a member of Cambridge Children's Network.
