Was Sarah Lynn stepfather abusing her?

I was rewatching the show and I know I might be extremely lay to this but there were some concerning remarks made by her about him. One is a memory she had when she was the sit of horsin around she says that her step father is a photographer who takes photos of her and he homeschools her!? And then she licks bear fur and says she knows it from a bear bc her stepfather was a bear!?
