Find a movie about witches in Europe and America

Nancy, Bonnie and Lou Cher are three unhappy students. They managed to get together because they couldn't get into the circle of other students. Sarah is a new transfer student. By chance, they became best friends and played "witch game" together. ...

It was Nancy who went to the mental hospital.

Sarah's mother is suspected to be a witch.

The main reason why they broke up was that Nancy used magic to seduce Sarah's boyfriend (? )

As a result, my boyfriend seems to be injured or dead.

Sarah thought they were terrible and cursed Nancy for using magic.

But failed, but almost killed by those three people.

So Sarah was angry.

Fight back ~ ~ ~ ~ Finally Nancy entered a mental hospital.
