Is there a spell to protect me from someone's bad plan against me?

Hey! There are quite a few depending on specific circumstances, but for a basis if you think someone is trying to harm you spiritually, I'd recommend investing in cleansing and protections as your first step, then maybe do a Return to Sender candle/spell. If its more physical, like someone is spreading gossip and you've already tried talking to them, you could do a spell to stop that, or even a honey jar to possibly sweeten the relationship? You can use a few different spells/charms in situations like these depending on the details. If you think you might be in genuine physical danger, I'd recommend reaching out to a professional as soon as you can. I hope this helped!
