Megan Robertson, of Burley, died on December 27, 2016 after telling her mother she was exhausted following a shopping trip, an inquest at Wakefield heard yesterday.
The inquest was told Megan had complained of crushing side-effects of anti-seizure tablets – including dizziness, nausea and extreme tiredness.
The coroner heard how the schoolgirl suffered from frontal lobe epilepsy which brought on night-time fits but experts said they could not rule out an abnormal heart condition as the cause of the teenager’s death.
After the inquest hearing, Megan’s mother, Samantha, said: “She was very popular and had hundreds of friends – many of them on Snapchat and other social media outlets.
“Megan was a gorgeous girl and is really missed – there was something about her you couldn’t help liking.
“That night I just went into autopilot – it was just horrific.”
