Auras and Headaches

I have no idea what in the world this is, and I'm really hoping to get some help. I've started getting these headaches. They are constant, almost always there, but sometimes they spike up into terrible migraines. I'm only thirteen, so I'm thinking they may be hormonal. This may seem trivial, but it's important.

But lately, my boyfriend and his sister (my best friend) have been getting sick. Both times, they've spiked dangerous fevers, and both times, I got these headaches that left me at home, locked in my room with a lot of ice and the lights off. They are my worst.

And also, since these constant headaches and migraines have been developing, I'm seeing auras. I'm aware that many migraine sufferers see spots, auras, or get really dizzy before the onset of a migraine, but I'm seeing them at other times. And with some of these, I get a knowledge.

I once looked at a schoolmate, and suddenly felt certain that a family member was once seriously ill, but brushed it off. I had this familiar whitish light that accompanies my headaches, and I went home later that day.

Later, we had a unit in science on cells, and our teacher was talking about cancer, and a boy made a joke about it, and the girl looked upset. I asked what was wrong, and she said her aunt had suffered from breast cancer when she was younger.

These knowledges are coming to me increasingly, and the headaches are growing more frequent, and worse, and I don't know if many of them are true, except for say, parents of friends. Every time I ask somebody something from their past, it's true to some extent or another.

And usually, these flashes come with severe nausea, if they are negative. It's really odd, and I don't like it. I'm going to see some specialists in the next few weeks, but I have been wondering if these things are significant, and if so, are they related?

I'm not really a believer in psychic phenomena, but this has me really weirded out...

Thank you!

P.S. Does anyone else hear people whisper their names sometimes? I might be having a joke played on my, but...
