Personally, I don't think Farrah was abused in any way.
"Abuse" to her was probably her mother not giving into her every whim and desire.
You know if she HAD actually been abused, she would be braying endlessly about it, who did it,
how many times they did it, etc.
She is vague about it because she is only insinuating - there was no abuse.
I think she was just spoiled rotten and never disciplined and she feels the world owes her something.
I really don't know what is wrong with her, TBH, or why she "cries" all the time.
