Searching for a story

I can neither remember the title or author's credentials

The story is about a transitioning adult MTF, comes out to parents, is rejected, brother molests/gropes at her breasts in front of everyone, she spalshes him with oiling hot water from a mug, I think tea.

Sister and mother all blaming her for what happened calling leaving messages to contact mom, to come back, to apologize, to 'give up this foolishness'. often calling her a psycho.

Meets new neighbour whom is a nontransitional but very passing FTM & practically spark up a relationship

appreciate the help, please
