Confused At What Is Going On

I do not really know exactly when it all started. I never believed in psychics at all. The most clearest time I can remember when it started was maybe 5 or 6 months ago. I was getting pictures in my head and certain scenarios playing in my head about a particular person. When I would get them I would start to shake and it created a feeling of being worried. I kind of just played it off because I just thought maybe it was just me thinking negative. Well I kept getting things on this particular person. I started seeing this persons personality change so I started asking questions. Well the answers came back to the pictures and scenarios that were played out in my head. I kind of panicked and did not know what was going on. As a little time went by I would still get these different pictures and different scenarios played in my head. All of them unfolded and were actually the truth on things that have happened and ended up happening. I started getting really bad head aches, to the point where light would hurt my eyes. My head would not hurt all the time but it was frequently. Most of the things that came to my mind were not very enjoyable or happy things. It was things I did not even want to know and I would just push it aside because the thoughts were emotionally hurtful. Everything I pushed aside always ended up true which I felt made it worse. I did not know what was going on with me. I felt confused, hurt, and a feeling of being cursed. The whole time psychic abilities never even crossed my mind. Here recently I got the courage to share it with my wife. I was hesitant because I truly did feel like a freak. I told her some things that were in my head about her and she was kind of amazed. She really does support me, this was only a couple of days ago by the way. A big part of me wishes that it will just stop but I can't seem to stop it. Last night I actually tried to embrace it, I was at work which probably wasn't such a great idea, and it felt too overwhelming. My head started to pound and I got a pretty good nose bleed. Today I tried looking things up about it and still do not quite understand it. I really do not want to tell people about this because I do not want to be looked at weirdly. I am very glad I found this sight and could put what I have been going through lately on here. Maybe someone could point me in the right direction. Like I said, I don't know why this is happening and what to do. Any advice would be greatly appreciated. Thank you for hearing my story.
