Ps 119 Look upon my suffering and deliver me, for I have not forgotten your law." When we suffer because of physical or emotional trauma  we must focus on Gods perfect work that He accomplishes through His law., We must realize that Gods work does not depend upon us. God never fails even though we are weak. God has ordered all of our days from before the foundation of the world. So God has  planned the times when we are gonna suffer in this life. Our trials in this life force us to focus on God by word and Spirit. When we meditate and pray our suffering drives us to be more attentive to the illumination of the Spirit. God will speak to us.
When we suffer our prayers are more passionate. We have no where else to turn. The suffering causes us to be needy and weak. God has made us for Himself. He draws us to Himself to find relief in our suffering. We feel like there is only one person who really listens to us.We need to lean on God in dependence and get our hope from His voice. So the Psalmist is saying that he must focus on a God who has everything in control. God is in the process of bringing all of  creation into unity.
