Blood Curse(s?)

Your name is Oscar Lily and ever since your thirteenth birthday you have had this mark on your chest, a contact curse of a witch within the party. You had collapsed from the burning pain in your heart when she said it was her gift to you. You awoke to people crowding you and seeing a dead witch on the ground, they lifted your shirt up and next ting you know everyone hated you. You are currently sitting in your room after meeting the local cleric, he couldn't remove it but he said the mark will be gone tomorrow and embedded in your heart. You are scared and alone, not even your parents want to be near you. Right now you are skimming through the book of curses and cures, but which section should you look through?
