It's possible that the ending is bittersweet. The daughter manages to get her life on track regarding drug abuse, but there are still some lingering issues. However, the mother and daughter have a stronger bond because of the experience. The Catholic radio remains a part of their lives, and they continue to listen for spiritual nourishment. The daughter may still struggle at times, but with the support of the mother, the church community she got to know through the radio, she is able to keep her drug abuse in check and strive towards a more positive future.
One possible ending could be that the daughter gets clean and starts a new life. Thanks to the support the mother got from the Catholic radio, she was able to find the right treatment for her daughter. The daughter, through counseling and spiritual guidance, overcomes her addiction and becomes an advocate for drug - free living in the Catholic community.
