The mother of a severely depressed teenage girl who died after falling under a train at St Pancras Station cried in court today on the first day of an inquest into the girl’s death.

Fifteen-year-old Tallulah Wilson, who was described as “beautiful” by her mother Sarah, jumped in front of a train at the station in Euston Road in October 2012.

The inquest at St Pancras Coroner’s Court heard that Tallulah, who lived in West Hampstead, had suffered from depression since her grandmother died in the summer of 2011.

She had allegedly been bullied for years at St Marylebone Church of England School in Marylebone.

She was pulled out of the school in May 2012 when her mother was told that it “couldn’t keep her safe” from self-harming.

She moved to the independent all-girls St Margaret’s School in Kidderpore Avenue, Hampstead, in September that year.

Her mother said Tallulah was “addicted” to self-harm and suicide blogs because she believed the virtual friends she had met online were the only ones who loved her for who she was.

A schoolgirl, who can not be named for legal reasons, said she made friends with Tallulah through a blogging website where they both wrote about self-harm and suicide.

The 17-year-old, who does not post on the blogs anymore, said: “I think something really needs to be done about [the suicide blogs].

“I had a close escape [Tallulah] didn’t, and other people are still doing it, so something really needs to be done about it.”

The inquest continues.
