[TOMT][MOVIE][2020s] Horror movie where girl’s mom passed away and she wore her dress to school then got liquid spilt on her.

I remember seeing this movie in theaters quite recently (past few years). There was a high school girl with brown hair whose mom passed away. She wore her dress to school and some milk or juice got spilt on her. She had people in her room smoking or drinking at some point. Her little sister had a creature in her closet or under the bed. Their dad lived with them.
