Ive noticed I’ve using this forum a lot to discern whether I’ve commited a mortal sin or not. Thank you all for your help with my spiritual life, though, it means a lot!

Anyway, this morning, when I was still in bed, I started thinking of this song in my head. Then I realized I should probably be praying instead, since it is the Sabbath. But instead of praying right away, I continued to think of the song for a little bit. Is this a mortal sin, since I knew I was putting something else before GOD? Thank you, and GOD Bless you!
Nope. A mortal sin is deliberate, free, full knowledge breaking of the commandments.
The commandment ‘honour the sabbath day’ means: go to mass (Saturday vigil mass or Sunday mass), and not do unnecessary work. It’s okay to do work like get stuff ready for school the next day, get dinner and tidy up,
So you haven’t even sinned at all!
The commandments would be:A mortal sin is deliberate, free, full knowledge breaking of the commandments.
The commandment ‘honour the sabbath day’ means: go to mass (Saturday vigil mass or Sunday mass), and not do unnecessary work.it would be a sin though to unnecessarily work all day at a job eg shop keepers, however some people have to work on Sundays it might be in their contract and I do not know would God count that as a sin.)

The occult, reading your star sign future in the paper or teletext, going to a fortune teller, hypnotist, reiki, biofeedback, yoga, Pilates (based on yoga), prayer centering (based on transcental mediation), or anything new age as all these things are occult, false worship or black magic,'or worshipping false gods, or letting something in your life become a sinful obsession
Honour your father and mother means, we are obliged to respect our parents (not sure exactly but some people say that means obeying their orders up to the age of 18yrs of age, but not if it’s sinful.)
Anything deliberately impure -impure music, masturbation, intercourse outside of marriage, homosexuality, adultery, pornography, even looking at semi clad people on magazines or explicit stuff on tv or in lyrics musc
