If she doesn't have the desire to read the bible, there are other ways of filling her mind with His spirit so that depression will flee from her. Play some nice relaxing Christian music around the house. Like, Have a little talk with Jesus, or One day at a time, so many to mention here, but those old ones are great to lift our spirits up and keep praying for her. Read her some of the uplifting Psalms too.
Lord lift away that depression this mother is feeling and give her the desire to get into your word and telling you all her hurt, and depressions so she can start communication with you and they can have a personal relationship with you. Lord if she is not safe have her come to know you as her Lord and Savior. In the merciful and mighty name of Jesus Christ I pray. Amen!
