So I'm writing this book about myself and my life. An unflinching look at the real lives of teenagers. and I did alot of stuff in this book. I was wondering how long after a crime happens is it legal to admit to it? Like, REAL serious stuff (not murder, but pretty bad stuff)

Step 01: keep the secret
Step 02: die with the secret

Even if you never wanted messed up things happen at that point it's all in your head and nobody knows a thing about it keep it that way if you want to improve things and try to make it right telling people would deny you putting things right you will pay your sins and it would make it worse if you tell anyone because it will haunt you mentally and in the real world as people become aware of that crime it's best to never commit the crime in the first place tbh
