Getting you back to life

Arnav has blamed her as the biggest mistake of his life. The family whom she had loved more than herself has literally blamed her for every mishap happened in their lives, her sister whom she had considered as her own was hand tied to do anything for her.
She thought for once, what is my life...?
Her parents had left her when she was too young leaving her to struggle in this cruel world all y herself....
Ofcourse, her maasi's family had adopted her as their own child and provided her with everything they had and could afford, they loved her immensely ....
She ofcourse was a jovial and loving person ....kind , soft-hearted.....but .....why is she so good? So childish ?....
She had built a wall around her mature self, engaged herself with her child like nature to protect herself from the demons inside her heart,
demons which had shown her the crueality of the world even before she knew what it was....
She was destroyed and devaststed even before she knew what had hit her....
But at the end of the day, when the only man she had loved with all heart had called her the 'biggest mistake' of his life....
She had always had this feeling of useless, unwanted, unloved, when her parents left her but she had somehow pushed out herself before she can fall into the pit hole of dark and depressing thoughts....but will she be able to do that or will she fall back and let the darkness and depression consume her.....
How is she gonna get back to life?
