Epilepsy ruins everything

The 10th school he's been to, the 8th town he's lived in, the second country he's moved to, the 0th time he's liked it.

Epilepsy is the curse of 15 year old Alex Walker, the only few gifts in his life being: his mum; his brother, Eliot; his sister, Eleanor (they were twins); his Shollie (German Shepard/Border Collie) service dog, Clover; and his headphones.

He was diagnosed with epilepsy at his first seizure when he was 4, his 6 year old siblings had found him seizing on the bathroom floor after looking at the flickering bathroom light for too long. His father had died when he was 5 of cancer, setting of a month of multiple seizures a week.

His mum had bought Clover, his service dog, when he was 7, as he was small and energetic and she couldn't always keep track of him. At the same time, she had also became a doctor and worker night shifts at the hospital, leaving her asleep most of the day. His siblings had inherited their fathers blonde hair and mothers blue eyes, while he had inherited his mother's light brown hair and father's green eyes.
His siblings, Eliot and Eleanor, had been born twins, and claimed sibling telepathy. Eliot had been born 20 minutes before Eleanor, always using that in their arguments, but he still never won, the only things they agreed on were helping their mum and little brother.

When Alex had been born, it was chaos. He was going to be born feet first (a big no no) and with the umbilical cord wrapped around his neck (even bigger and deadlier no no), so she had had an emergency c-section.
Oh yeah, and he had also been 3 1/2 weeks early, so he had to be incubated for 3 days as he was so small and fragile. When they brought him home, they had to take turns keeping an eye on him, only being able to stop when he was 2 months old.
His siblings were born on January 1st, while he had been born March 2nd.

He had been homeschooled by a tutor at his house from the ages 5 - 7, at 7, he was allowed at school, with his dog as well, of course.
