Conundrums

Here is a hypothetical conundrum.

If I in my youth was so critical of my mothers smoking that due to unknown or unforceable curses, I was cursed to smoke and I who born of a great princess; my mother, thereby inheriting great princehood and by the curses that are laid out as a defense for me, my mother was also cursed by those same curses now laid up in her bed and growing weaker also. If I quit smoking the curses that protect me having proved stronger would cause my Mother to die.

Leaving me in a place where I have the choice of quitting and by proxy of the curses killing my mother or continuing to smoke, slowly killing myself.

Which choice should I make?

By the way I am still smoking.
