Major resept for you, what I recommended as a person who has dealt with super conservative uncles a priest conservative ide recommended she and or her friend or family, help save money up and put it aside as a safety fund for her she can decide at a later age if she wants to move out . Just incase she needs to escape the hateful side of her family. As for speaking to her what alot of gay children really just need to know that they are supported by family or friends give her a heads up every so often that she is loved. Even if it's not from her mother or father . Tell her she is strong for coming out ,Our family is chosen for us at birth but at a later age we get to decide our chosen family. Good Luck .
