The only thing that can remotely help you in this scenario is stay with your uncle and create as many memories with him that you can(videos, photos, etc.). That is what helped me when my father passed away from lung cancer, but I did not had as many forms to make thing that would help me remember him by since when he passed i was only 13, now I am in my early 30.
The mc must have a harem đ, the Greengrass family is not part of Voldemort's circle only Lord Greengrass father of Dafne and Astoria does and he led the family to join him so take the Greengrass family from the Malfoys and the other psychopath is a good one and it has the curse of sange de astoria that the mc can break, the bones family is also good to save amelia as this involves the family books that was soul magic I know it has nothing to do with the chapter but just to remember
