A bullied Staten Island teenager threw herself under a train yesterday as her horrified classmates watched on.

Felicia Garcia, 15, sobbing, leaped to her death at around 3.15pm at the Huguenot Staten Island Railway station platform, which was packed with fellow Tottenville High School students.

The teen, who friends claimed had long been tormented by school bullies, in particular football players, tweeted on Monday: 'I cant. im done. I give up.'

The same day she posted photographs of herself on Instagram where she appears beaten and bruised, with her lips seemingly cut or sewn together. She added the hashtag 'beatup.'

A friend, Alissa Compitello, tweeted yesterday that the relentless bullying Felicia was dealt at school had driven the student to take her own life.

'SHE WAS BULLIED... SHE WOULDN'T HAVE DONE IT IF SHE WASN'T BULLIED,' the teen wrote.

Earlier, Compitello tweeted: 'All this girl wanted was to be left alone... and nobody could do that for her. #prayforfelicia.'

Another pal, Domenica Modica, said her father carried Felicia to the ambulance stretcher and tried to revive her before she was rushed to Staten Island University Hospital.

She was pronounced dead just before 5pm.

Friends claimed football players at the Staten Island school were behind the destructive bullying, claiming they targeted her because 'she looked different and had piercings'.
