I need help with advice on what to do about my situation?

Its not upto you! All you can do is give her adivce and direct her to taking the right path. Love is a tough subject and you can put up with so much crap by loving someone. If she wont help herself there's nothing you can do and you can't put your life on hold. Support her whilst you can.. tell her she deserves better. She will eventually realise, it just takes a while.
