In one word, one should desire of God desirelessness. For desire alone is at the root of all suffering. It is the cause of repeated births and deaths. It is the obstacle in the way of liberation.
No one can suffer for all time. No one will spend all his days on this earth in suffering. Every action brings its own result, and one gets one's opportunities accordingly.
Even Avataras, saints, and sages have to undergo the ordeal of suffering, for they take upon themselves the burden of sins of omission and commission of ordinary human beings and thereby sacrifice themselves for the good of humanity.
Don't be afraid. Human birth is full of suffering and one has to endure everything patiently, taking the Name of God. None, not even God in human form can escape the sufferings of the body and mind.
