Let me redefine heartbreaking :
A father killing his all desires to provide to the family & still feeling sad when he is sometimes unable to fulfill the wishes of his children cz he can't afford it.
Nahi Hai Honsla Mujh Mai Tumhain
Khony Ka Par Sun Lo...
Ye Dunia Mujhy Kho Dy Gi Agar
Tum Kho Gaie Mujh Se.....!!
Sometimes you hurt yourself more than anyone could hurt you, only for keeping your feelings hidden.. :(
