"'Why is light given to those in misery, and life to the bitter in soul, to those who long for death that does not come, who search for it more than for hidden treasure, who are filled with gladness and rejoice when they reach the grave?'" NIV translation
Job now has the attitude of "if only it would all end" as he has accepted God's will in giving him birth and the life that he has led so far. But, now, he asks the question of why God does not just "call him home". This is still a struggle in his mind with the sovereignty of God and the fact that God has him going through this for a purpose.
At some point in our lives, we have all probably had this same type of struggle. We must remember and realize that it is during the toughest struggles that we learn to rest in God and grow in our faith.
Job was thinking that it would all be better if his life on this earth would just end but, once again, he does not know everything that God does.
This same type of crying out for life to just end will occur again during the Great Tribulation where, at that time, the people on the earth will cry out for the mountains to crush them to save them from the wrath of God (see Revelation 6:16).
"'Why is life given to a man whose way is hidden, whom God has hedged in? For sighing has become my daily food; my groans pour out like water. What I feared has come upon me; what I dreaded has happened to me. I have no peace, no quietness; I have no rest, but only turmoil.'" NIV translation
In a way, Job is once again acknowledging the power of God as he recognizes that God is protecting his life but he just does not understand why. We see that Job describes his fear and we are reminded that fear is not from God but is a tool of the devil. He describes how his peace and rest through his faith in God is being taken away by fear. When we see fear creeping into our lives, we, like Job, must remember to rest in our faith in the goodness of God.
