Oh shit! That's crazy man? But, one thing that you have to do, is to not show fear to that parasite, and show it Love. For example: meditate with the parasite, and visualize a beam of Light, but you have to put your intention on that Light with Love. If that does not work, call upon The Universe as Jesus. I'll give you an affirmation: say this. "My Ultimate Source, I call you in the name of Jesus, for your aid at stopping, and taking these parasites out of me. Please, help me." Try to say it exactly like that. Once again, don't show fear or else chances are they won't want to leave, and also don't show hate towards them, because they will keep on arguing with you, and get louder. You can do it.... I believe in you. So do that and let me know, how it went. Best wishes!!
