I had an idea for a play, and I acted upon it. I've developed characters and a setting, but my plot/main character is really flimsy. Basically, she somehow gets her whole family to hate her as she's becoming a worse and worse person. She almost lets her sister die (let her drive home drunk), freaks out on her boyfriend (her reasoning: he was spending more time with his dying mother than her), boyfriend broke up with her finally due to the fact that she lied about kissing her best friend, she curses out her mother, and tells her best friend that he's "weak" after his sister's tragic death. She also makes everyone's life a living hell, just being rude. Anyways, this all leads up to a final scene where she realizes everyone hates her, contemplates suicide, BUT there's a big reveal where her best friend actually kills her. I honestly feel like the main character's sudden nasty change in personality is flimsy, and that her best friend has weak motivation for killing her. I'm just asking for thoughts on this, and where I should go from here. thanks!
