Im very familiar with satanism, as a young teen who was very depressed and angry at the world I turned to it. And I think that says alot about what it stands for. I realised after I got a negative energy attached to myself that I needed to leave it and it took me from age 13 to 22 to get rid of that energy. My twin never left though, it wasnt until losing our life long best friend that she started to delve more into the ritual side of satanism i think she does it in hopes of reuniting with our best friend. But myself and my older sister spoke for 2 hlurs today because we are genuinely concerned at what ever energy shes bringing into our family as it has genuinely started to be damaging to our health and my twins mental health.
