Was this movie plot a fever dream or can I just not remember?

I need to know if anyone can remember the name of this movie or did I make it up. All I can remember is the plot follows 3 mean girls who I’m sure all share the same name and I think it’s Helen and the main one is blind, she’s played by an actress with short hair I think. And I also think she gets murdered by getting pushed through a glass table. Please help me or tell me it was just a wildly vivid dream.
