"Who are you writing for?" is one of the prime questions in any writing. I don't believe it is something we have to worry about too much in rough draft, but as soon as we begin revising, we need to be considering who this is for. Not just why, the deeper reason why, but to whom we are writing.
It's a hard question, though, because audience can't be too big or too small. "Everyone," is not a working answer. Too vague. "My sister," is too specific, though you can find clues in there. Why your sister? Because she, too, survived an abusive childhood? In that case, maybe you are writing to people who survived abusive childhoods. A somewhat narrow (though not narrow enough, unfortunately) audience, but getting closer. Perhaps then people who want to know what it was like, not just survivors. Ah, now we are getting there - an interest group, an audience, big enough to be diverse, small enough to have focus.
