Call out to Jesus from your heart. Ask Him to give you enough light to discern His will.
Read St. Faustina and St. John of the Cross, a paragraph every day. This, and prayer, plus time spent in adoration of the Blessed Sacrament, will help.
Go to You Tube and search for "Where have you hidden, beloved?", by John Michael Talbot. This is a song about the darkness that Talbot composed by setting St. John of the Cross' poem to music.
Be assured of my prayers for you. It is in those moments of darkness that Jesus is closer than you realize. Remember St. Theresa writing about being used by Jesus as a child does with her ball. Sometimes the child plays with the ball and other times the ball is left in the corner. Focus on the Agony in the garden and picture Jesus being completely alone because his disciples slept. Unite your sufferings with His and truly you will be blessed.
