She needs someone who will take her to a counsellor and get her professional help for overcoming her depression.
She needs a tight mental slap from someone to bring her out of self pity and undue guilt.
Poor girl is stuck with idiot of a family. A mother who...(jaane do at serious loss of words for her) A father who is spineless himself and asks so lamely to be brave. A brother who "understands" his sister so "well" but absolutely does not know how exactly to help her. A step brother who is in such a magnanimous mood he will loan his fiance to be his own brothers temp wife!!!
You know what I really feel with such "supportive" family, she will really always face defeat!!!
