Feeling the Pain: 1

When a person is in pain, God feels his pain as well. Even though He is aware that the suffering is for the person's own good, and the suffering is only due to the person's lack of understanding, still the reality is that the person is suffering, and God suffers along. It's similar to a parent who is feeling the pain of a child taking unpleasant medicine. The child is crying and the parents know it's for his own good. Even though logically they know there is nothing about which to be upset, they feel it.
In the same vein, if a person is troubled about his spiritual state - by feeling that he is not achieving his spiritual goals - God feels his pain as well. Why focus then on one's (perceived)  lowly state; why feel distant from God who he views as standing angrily wondering why the person isn't closer? Why not focus on the truth that as he is in pain due to his spiritual state God is right there with him feeling it as well!

The Importance of Relationships: 4b

After a person finds enjoyment in being alone with Hashem he will not find any other place of refuge in the world. Nothing will give him satisfaction and relaxation like a moment alone with Hashem. When he is lacking this pleasure he will find himself hungry and desiring that taste of life. Everything else seems empty and dry in comparison; he only wants to feel that connection that he had when he and Hashem were together. (These hopes are what build the eventual connection.)

This is the idea of התבודדות, Hisbodidus. On the one hand the person leaves civilization to go out in to the fields, under the sky. He is like a beast seeking and crying out for his sustenance. On the other hand, this is where he finds his true life.

He will seek out every bit of life he can find in each word of Torah that he studies, in every Mitzvah that he performs, in his every word of prayer - in all that he does. It is all revolving around his ultimate goal of finding a resting place for the Schechinah within his heart.
