Hello, negative and hateful people can drain your energy and effect the energy field by blocking the energy and weakening the chakras. What can help is taking a sea salt bath with lavender essential oil. Salt and lavender essential oil removes negative energy you have picked up from others and the environment. Also, you can wear a crystal or gem stone. You can buy them cheap at your local metaphysical shop or online. You can do a Google search for healing crystals, and there are websites that explain how each crystal will help with certain energies. Wearing or carrying crystals will help to protect your energy.
