Start by focusing on the positive instead of the negative. Release any negative energy inside you, as well as outside of you. Instead of telling your angels to stop letting bad things happening to you, thank them for the blessings in your life and ask them to keep you safe.
Use bloodstone to absorb negative energy directed your way and black tourmaline to create a protective barrier from everyone else. Keep away from gems that will magnify the energies around you, including clear quartz, citrine, and amethyst - pretty much any gemstone connected to fire.
