A Queens woman whose daughter attempted suicide after she was mercilessly bullied at school is suing the city.

The 16-year-old, a student at Robert F. Wagner Jr. Secondary School for Arts & Technology in Long Island City, swallowed a bunch of pills in a desperate suicide attempt after taking a beating, said her mom, Jennifer Jimenez.

The mother claims her pleas to get the bully out of her daughter’s class fell on deaf ears.

City lawyers declined to comment.
