Q. Is there anything I can do to get rid of this awful fear that I will never be good enough to get into heaven?

One thing that is clear in the gospel is that Jesus came to save all sinners. Let him be your Saviour, the Lamb of God who takes away the sins of the world. Accept the divine forgiveness which is celebrated in the sacrament of Confession. Instead of you trying to get into heaven, why not let heaven get into you. What I mean is that you allow God’s love and mercy take over your mind and heart. Don’t be all locked up in yourself but let God’s love take over.
