Now, desperate for a diagnosis, she is sharing her story in the hope of getting her life back. Miss Harvey's ordeal began in 2013 when she woke up with blood spatters on her pillow.
Her terrified mother Catherine, 43, took her to the GP - but despite several tests, no cause could be found.
For the next two years she was sent for more investigations and told to change her diet, eliminating food groups from sugar to dairy, in a bid to find out what was causing her symptoms.
But her condition continued to get worse - and in July last year she was horrified to wake with 'gloopy' blood seeping from her eyes.
She now bleeds from her eyes, nose, ears and fingernails up to five times a day - but doctors from every area of medicine are baffled as to why.

Miss Harvey struggles to open her eyes as the blood stings. It caused her family to scream the first time it happened in 2013
In the last few weeks, she has also started to bleed from her tongue and scalp.
Miss Harvey, from Stoke-on-Trent, is thought to be the only person in the UK with this unique set of symptoms, causing doctors to dub her ‘The Mystery Girl’.
Recalling the moment she woke up with her eyes bleeding, Miss Harvey said: ‘Red, gloopy tears were dripping out of my right eye.
'I had blood all over my face and a shooting pain behind my eyes.
'I felt my way downstairs and my parents, brother and sister all screamed when they saw me. My brother called an ambulance.’
