Sorry It Had To End This Way

there was a girl. her name was isabelle. she had a very strange obsession. her obsession was blood.everyone thought she was wierd. they called her names and beat her up. but one day she had enough. there were several people she had in mind to kill. first up: her mom. her mom did the same thing everyone else did. called her fat, beat her, did everything in her power to break her. but instead, it just made her angry.
she walked into her mom's bedroom. no words were spoken. she grabbed the knife out of her pocket and stabbed her in the chest. she died instantly. but that's not all she wanted. she wanted the blood. she wiped it all up with a sponge and drained it in her mouth. disguisting isnt it. but she didn't care. she walked away, smiling the most demonic smile you had ever seen. killing had changed her. but it would soon change her even more.
