Why Maynard are you quoting from the Catholic Church?
Where in the Scriptures does the Holy Spirit say, "Grave psychological disturbances, anguish, or grave fear of hardship, suffering, or torture can diminish the responsibility of the one committing suicide. "????? Where in the Scriptures does God say this? Show us the Book, Chapter and Verse in the Scriptures where God says this.
Its what the Holy Spirit says in the Scriptures that is the Truth, not what the Corrupted Catholic Church says. All you are quoting is what the Catholics say, not what God says
Sola Scriptures only. Opinions of Popes are not Truths from God, they are just opinions from sinful people.
