I know all about the despair of overcoming chronic temptation. It is not serious, provided self-offended petulance, annoyance at breaking records, impatience, etc., don't get the upper hand. No amount of falls will really undo us if we keep picking ourselves up each time...The only fatal thing is to lose one's temper and give up.
C. S. LewisChristianity tells people to repent and promises them forgiveness. It therefore has nothing (as far as I know) to say to people who do not know they have done anything to repent of and who do not feel that they need forgiveness.
