Am I Talking To An Angel Or A Demon?

This is really weird but I can talk to my guardian angel via telepathy. I met her about 2 years ago. We became really close friends. My life was bad back then, but when I met her, my life SUDDENLY BECAME MUCH BETTER. She grants me wishes, scolds me when I lie or say bad words. She is basically a mother to me. By the way, I am 15. When I'm sad, she cheers me up. I am insecure about all of stuff so she counsels me about it and she makes me feel MUCH better. She sometimes tells me test answers if I was begging her, but she rarely does that cause she says that's cheating. Like who cares. I got every answer right on the ones she told me the answers on. I sometimes think I'm schizophrenic, but she says I'm not. Sometimes I ignore her because I think she's just imaginary but then she gets annoyed with that. One day my mom injured her spine and the doctor said it is not curable and then mom started crying. But then I asked my guardian angel to cure her, then the next day, my mom woke up with a completely fine back. She was REALLY HAPPY. She says she wants me to be happy, because she has seen how disgusting my past was. Divorce, don't even remember my own father, abuse, felt no parental love, nothing. About 2 years ago, I was about to commit suicide by overdosing on pills and then I heard her voice. That's when I met her. She tells me to forget everything that happened and move on because the past can't be changed. She told me everything about what happens after death, Satan, Gods and etc. She said there are good demons and bad ones, just like humans. I feel her presence, and I want to hug her but I can't. I really wanted to see her so she introduced astral projection to me. She said we could meet when I astral project. I can't astral project because ITS SO HARD. But I'm still trying. The weird thing is I never had a dream about her. Never. She says she can read my emotions by looking at my aura. Now she is telling me that judgement day is sept 2015. She says there is a reason why we can talk to each other. She said I have a role in the judgement day prophesy which goes against antichrist. She hates antichrist. She told me that he already exists and is deceiving the whole world, and that ticks her off. She I will be able to fulfill my role in the prophesy by having magic. So she said I'm going to get magical powers soon. I said that magic is against gods will. But she said there is no other way to fulfill my role in the prophesy without magic. She said I have to face antichrist face to face which is weird. She said that she was in several of my past lives, as an angel, not human. Like I could see her and she could see me in those past lives. I have faint memories of them. Like one where my family was killed In a huge palace and I was a child. I have recurring dreams about my past lives but then I wake up crying, I don't know why. I don't even remember why I was crying. The dreams aren't clear though. She says she is protecting me from an illness, the cool thing is that I haven't even gotten a cold since last year. She said I'm her best friend. I feel positive energy when I talk to her. She says she is also protecting my from Satan, because Satan wants me dead before I go against him and his antichrist. It's true, she is protecting my whole house with a spell. She said there are 3 arch angels guarding me until I get my magical powers. After that they will leave because I would be able to protect myself but my guardian angel would stay with me, to fight against Satan with me. She says it's not mandatory to fight Satan but it's mandatory to go against antichrist. She says god chose me right before my birth. It's weird. She told me stories to me about what happened when my mom was pregnant. When I told my mom the stories she interrogated me on how I knew such stuff. I told my my that grandma told me, which she didn't.
