When it comes to being an empath, I would suggest working on prayer and visualization for yourself. I have to visualize a white, shimmery light (holy spirit, or what have you) over me that settles over my skin and turns into armor. It gives me strength. In regards to the woman working against you, I wouldn't suggest any spell work unless you have experience with that sort of thing. We come into this life to learn lessons, and sometimes the lesson is in setting boundaries and standing up for ourselves. You can pray for her all you want, but she still has free will. If this woman is in your life to teach you something, your angels and guides won't interfere. Ask them how to deal with this situation and ask for strength. What are supposed to learn from this woman?
