I agree with Megan’s advice to see a doctor. Science and faith work better together than separated.
Also, I might be a lone voice on the forum to say what I’m going to say but I hope it helps.
While there are certainly “emotional 
vampires” and toxic people that we need to cut out of our lives and protect ourselves from, no one has magical or psychic power over you. None of that would ever work. You are equal to all other people on earth. 
You are a child of The Divine - however you understand it. Nothing stands against you in the spiritual realm.
