Confused Psychic

I'm 13 years old and I'm psychic. I'm clairvoyant, a clairaudient. I feel energy, I see demons, and I think I influence things.

I've spoken to a lot of people, and they've all given me completely different answers to my questions.

First, I'm unsure if influencing activities, choices and outcomes is a psychic power. I think it is, but I can't be sure because one day, while I was sitting in French class my teacher told us in two days we would have a massively important test, and it would have a big percentage on our overall grade in the subject. But I had been sick, and I had missed six days worth of any warning, so the day of the test-after forty eight hours of cramming- I still knew I wasn't going to get a good grade, or pass at all, so I kept chanting; 'Please let the test be cancelled,' over and over, and after all the stress, my teacher put the test off until next week, no explanation, he simply cancelled. And I got almost perfect on it.

Secondly: I've asked many psychics and mystic believers their opinion on demons, and they said they don't think demons are personified the way I see them. They look like crippled humans, or they're cloaked. They also tend to stay in darker areas, like in shadows, or they appear at night. The first time I saw one was when I was outside, and it was getting dark, and I was with my friends. We were on our way to a store down town. Then I saw a demon in a shadow of a building, at first I thought it was nothing, some object in the shadow, but I realized it wasn't normal. I asked my friends if they saw it, and one of them asked what I was talking about. I said never mind, and suddenly a horrible headache started and I felt weak. Any insight or advice?
