Remember the compassion of God, how he heals. Do not despair of salvation. Recall the memory of what has been written, how he that falls rises again, and he that is turned away turns again, he that has been smitten is healed, he that is caught by wild beasts escapes, and he that confesses is not rejected. The Lord does not want the death of the sinner, but that he return and live. Do not be contemptuous like one who has fallen in the depths of sin.

–Basil the Great, Letter 44

Basil is onto something very important here. One of the things Satan uses to keep us in despair is distractions. We get so distracted in our daily lives that we forget the promises of God. We forget to recollect ourselves before him. We forget his mighty acts in history so that we can live our days in hope and expectation. That is why remembering is a consistent theme of the Bible. Remember the goodness and mercy of God. Remember the Good News of Jesus Christ. Be intentional about it, especially in the midst of your distractions so that you do not fall into despair.
