I have a serious question,
I know theres many ways to break the harm none rule, and I know one of them involves harming yourself.
Many people are probably familiar with Self Injury, or cutting. I've done it for years, even before I started witchcraft.
I don't want to do it because it does break that rule but its so hard to stop.
I was able to stop in 2010 when I first came to witchcraft, and I stayed that way for a while until I ended up in a abusive relationship. I want to be able to stop again.
I was wondering if anyone had any sort of spells, meditations or rituals that could help me, because I feel like I shouldn't practice witchcraft if I keep breaking the main rule.
Thanks for your help
blessed be
