According to the police she requires regular injections of insulin and went missing with medication, sufficient enough only to last until yesterday.
A police spokesman said: 'Stephanie normally deals with her condition in a proper manner. However, her failure to return home last night, and her medication running out today, suggests she may seek help from elsewhere or she could be ill.'
He also added 'The public should be aware that diabetics without insulin can show signs similar to that of someone under the influence of drugs or alcohol.'
'This would be a clear sign that Stephanie requires urgent medical treatment.'
