YOU'RE CAT IS SO CUTE
You just inspired me to do the same thing with my cat, especially since it's new years
I don't know if I can be much help but, you could research different religions and find if any of them are something that make sense to you and that you would believe in, but don't force yourself to believe, otherwise you'll be left with doubt and I don't think that would solve your problem.
If that doesn't work, you could try to find peace in you......
