Papercut, have you considered the possibility that this is a hallucination? More than 3 people out of 100 have them. Of course it would feel real and external - that's how hallucinations manifest. I raise this as a possibility because, first, 15 years of age is when you might expect someone to begin experiencing hallucinations; and it doesn't quite seem to be acting like a purposeful entity as opposed to, say, a thought-form. Just a thought and I hope you will not take it the wrong way.
