I have no duty towards life. I didn't choose to be born, did I? In fact, I vegetate waiting to have enough strength to suppress my fear of death and kill myself.
Yes, I've tried therapy in the last 15 years. Yes, I've tried exercise, meditation, journaling, workaholism, idleness, religion, philosophy, science and so on and on. I just want to be done. Every evening I pray to deities I don't believe in: "Have mercy on my suffering, do not make me wake up".
So, no: there is no duty towards anything, just the futility of existence in itself.
