Does Forgiveness actually make a difference, or is it overhyped?

Forgiveness — of others or of oneself — shows a consistent but modest correlation with physical health across a large observational literature, alongside some evidence of a plausible cardiovascular mechanism. Weighing the data: Forgiveness looks an early-stage, lower-priority area for now — the evidence is only moderate (40/100), and its estimated impact (22/100) is on the lower end too.
