How to get them out of my mind and away forever?

Now, I don’t want to believe in hexes or witch craft. But my grandma and aunt don’t escape my thoughts. They have been very emotionally abusive to me and my mom begged them to stop. I believe they were jealous I was born in America and they weren’t. They give me a lot of gifts or my aunt does now. My grandma stopped, but my Vedic chart says my maternal line (them) has witches in it. They don’t escape my thoughts. They are very self serving and favor only my aunts kids. They are takers. They come to my mom’s home and act like it’s theirs, trying to make me feel uncomfortable. If I ignore my grandma, she tells my aunt and the triangulation starts. I’m tired of them. I’m tired of them in my thoughts.

I wish they never came to the US. Everything went horrible once they came. My dating life was weird. My career isn’t moving forward. I’m not passing my exams. They think they are all that. My own grandfather died at a very young age. So many things point to them being a strange force in my life that I can’t handle anymore. How to protect myself? How to get them out of my mind once and for all?
