Asking For a Little Help..? Please

Hey there. Followers and Friends.
See, I have a little problem... Maybe someone out there can give me some relief?
I know that this may be a little long, but if you know anything about headaches or migraines, please read this. Please.

I get headaches. Pretty bad Headaches.
     I have gotten average headaches since I was a kid. They never bothered me much, you know, most people get headaches once and a while. About 4years ago. I started getting more frequent headaches.
I was in high school and often I didn't eat school lunch. Id eat when I got home so I didn't mind. But when I started getting headaches my mom got worried and said that I needed to eat at school. I did from then on. My headaches stopped somewhat. Then a few months later, I was getting painful headaches. Headaches that hurt bad enough that I needed to stop what ever I was doing and put my head down. I would take medicine (Advil, Tylenol, what ever we had) and it would stop the pain.
Soon my pains were even more frequent. I was getting a headache almost every week. I wear contacts instead of glasses, so we went to see if that was it. I got an updated prescription and I could see fine. Still, my headaches pained me. I would go days without my glasses or contacts to see if It would make things better. Sometimes, it seemed to help. But really, my vision had  nothing to do with it.

  
*****  Let me jump to this past year. This year, my headaches had been picking up more.
See, by now I had seen doctors and taken medicine after medicine. Still, my headaches continued. I even had a reaction to one of the medicines my doctor prescribed. My headaches now happen almost on a daily basis. It is rare to go a full day without a headache. The pain in my head doesn't happen in a specific place. The pain happens on the left, then the right, in the back or front or center. It happens at any given time and Now, Even medicine has no effect on the pain.
     I often take Ibuprofen and I even take one more than it suggests on the back, still, my headaches don't change. The pain often lasts about 5minutes, then goes away quickly, then comes back.
But sometimes the pain can come and pain me for hours strait with little relief. Taking medicine may have an effect, but to my own knowledge, my headaches vary too much to be noticeable.

Things that seem to set it off?
Noise and change in elevation.
I once went to see my doctor about how sometimes, when I use to sit down or stand up quickly, or even slowly sometimes, I lose my vision and I become very dizzy. I see black and have to hold myself to stay standing. She told me that was normal and that she even gets that.
But now, when that happens, it triggers my headaches.

They say it I don't have migraines because I don't have enough of the symptoms.
Light does not effect it, and Iv'e tried Migraine medicines and they don't help.

     I went to try and see a neurologist. They denied me.
We tried again, and we were finally able to get a Scan. I forget the name.. It is similar to a CAT Scan. It was like, CT scan or something. They stuck me in a Big scary white spinning machine and had me lay down as it shot radiation into my head. The woman even said, "Okay. Now you lay here and we will go outside where it is safe to prevent from radiation exposure." Then left the room and stuck me in the machine.
They found nothing.
Just a little abnormal dent shape in one side of my brain, but that doesn't seem to mean anything.
We left. No news.

     We went back eventually on a day that we had an appointment to meet with the neurologist finally. Finally, we were going to be able to explain to someone what has been happening and maybe they can help me.
Right before we go in, the receptionist person calls us up and says I have no health insurance.
Apparently, because of a situation, My health insurance had ran out that day.
That means if I want to see the Neurologist, it could cost us thousands of dollars. Just a few hundred to talk to them.
Just the luck of it.
Wonderful.

I write this today because I woke up with a headache as I often do.
I am afraid that they are getting worse. It pains me so bad I can't even lay down to make it go away. Cold towels don't help. Medicine is useless.
What do I do?

I am very scared, what if I am going to have an Aneurysm any day now?
Thanks to America's Health care system, I can't even prevent myself from possibly dying. Thanks. Thanks alot, America. Gah. I want to be living in England.

Please. What do you know?
Can you help me?
