Unless you are a person who has chosen to be a Catholic.
Then you can have confidence that all the unique Catholic rules will keep you in a state that salvation will be granted to you at sometime in the future.
The best part about being a Catholic is that when you die, your relatives must continue to go to the annual mass of your death, and if nobody shows up - you lose Purgatory and go to hell.
I had an aunt who died years ago. First anniversary of her death mass about 12 folks showed up. Next year maybe 4. I suppose she’s in hell now since they outright cancelled it last year.
