Is It Normal Not to Feel Joy After Repenting?

“The joy of my salvation just doesn’t come. There are times when I don’t feel it, even though I repent and walk in purity. It seems that the joy of salvation in the Christian life remains elusive. I see Psalm 51 addressing this. What should I do when I have repented biblically, but the joy still doesn’t return? Is there some sin I’m unaware of that’s holding it back?”
