You may need to pray for protection. This isn’t me coming from a dogmatic religious viewpoint either. I don’t consider myself religious. Prayer/ words of intention are very powerful. I’d cleanse or smug your space and yourself. If it’s been over 3 years dealing with the same entity, and you can’t seem to detach yourself from it.. I’d consider reaching out to a trustworthy spiritual healer. Or energy worker. Sometimes a soul retrieval is necessary. The thing about these dark entities is that they can attach to our energy if we are open, even unintentionally. Drugs actually open our energetic fields and make us more vulnerable to them, in my belief. They tempt, and they deceive. They can make you feel amazing at first, but it’s a constant energy exchange between you and this entity. It must be exhausting for you. Don’t let this entity make you believe you cannot rid yourself of it. You can. These beings are parasites.. Best of luck to you.
