She's probably trapped living a life that isn't her choice... because of life's circumstances. Someone like this needs spiritual guidance, and/or a GREAT friend.
I say, live with passion and when life throws you lemons...make lemonade! Happiness is Fleeting!
Overall, it's best living life happy than miserable.
Everyone has a black cloud over them sometimes, but one has to focus on the silver lining... it's beautiful.
LIFE is Precious!
