This is just a list, and conditions apply, especially regarding Divorce in Civil Court.
Here we go:
|Adulation of another's sin||Bestiality||Blasphemy|
|Cheating and unfair wagers||Envy||Contraception|
|Defrauding of a just wage||Divorce||Extortion|
|Practicing magic or sorcery||Hatred||Fornication|
Mortal sins require absolution, so check with your Priest. You may have some trouble getting clarity after you commit suicide.
Again, ALL YOU HAVE HERE IS A LIST. I'm not making any judgments and don't consider me an authority.
You might want to check with sources like The Congregation of the Doctrine of the Faith
Also, you can find the scholarly literature about sin in the Catechism:
PART THREE: LIFE IN CHRIST
SECTION ONE MAN'S VOCATION LIFE IN THE SPIRIT
