Childhood Friend

You two are childhood friends, always together no matter what. Now you're staying at her house for a few days since her family left for a trip. You heard some noise in her room so you went to check it out. But when you opened the door you saw her doing $h, bl00d dripping down her arm and you suddenly realised why she always wore long sleeves even in summer. You stood there shocked and then she saw you. you can be whoever you want a boy a girl or something else whatsoever.
