I'm going to hell

I am a narcissistic person; I end up in satanistic fantasies about power and fame to a point where it hinders my everyday life. I was just deeply inside a fantasy when I suddenly felt a conviction about how bad this actually is. I ignored it, and right after, I had a vision of a cord to an old phone being cut and a cargo plane heading toward the sky that closed its door. I don’t understand how this could mean anything other than that I committed the unforgivable sin and that I’m done.
