You can simply get someone out of your life, someone who may just be annoying you or bothersome and not any real threat to you, a banishing spell is your easiest option. It causes no harm to the other person, and simply gives them a magical push away. For something a little stronger, you can go with binding spells to prevent them from acting against you.
If the problem is more aggressive, and you think someone has cast a negative spell against you. Then you would want to take a different approach. You can either try a curse breaking spell to counter-act any hex or black magic. Or you can actually reverse the spell and send the negative energy right back to the person who sent it.
Do not rely on magic alone if you are in serious danger. If you are ever truly threatened, stalked or harassed. you should contact the police always before relying on a spell for protection.
Banishing Protection Spells
Banishing spells are much like binding spells in that their intention is to keep someone out of your life. A typical spell like this will block or push someone away, unlike the binding spells that usually involve cords and knot work.
Binding Protection Spells
These spells are any kind of magic that you use to force your will on someone, usually to stop them from doing something. Binding them up makes them powerless. One exception would be with love spells. A binding love spell is one where you bind a person to you, and basically make them fall in love with you. But on protection spells, a binding spell is used to keep someone from doing harm to you or your family.
Protection Breaking Spells
Breaking spells are intended to break a spell that has been cast against you. So if you feel that someone else is using witchcraft to cause you misfortune, these are the spells you want to try. Banishing spells may keep someone away from you, but they will not break any curse or hex already created. And please remember that not all bad luck is caused by someone else cursing you. Yes it can (and does) happen, but be reasonable when trying more magic just because a few things go wrong for you.
