Everyone I care about miraculasly gets ill when they date me but recover if they leave?!?

Ok so the past 6 guys I have been with got ill and nearly or did die. The more I care about them, the more life threatening what happens to them is. I told a wiccan ordained minister about everything that has been happening to me (to much to write) and he said he thinks a demon is following me and targeting the people I care about. What do I do?!
