I hit my head very hard yesterday, help me please?

2 years ago, I had a coup-concoup concussion (I think that was how to spell it). Ever since then, I've had a never ending headache. It's even in my dreams. I also get migraines where my brain smacked the other side of my skull. Then last Christmas, I hit my head on my temple and got a minor concussion then. But there didn't seem to be any lasting remarks from that. Anyways, yesterday I plopped down on my bed and hit the back of my head on my windowsill. When I hit it, I felt something hit the back of my right eye. I have a terrible headache, so much worse than my normal headache. I'm extremely nauseous. I can barely read small print (my dyslexic boyfriend can read better than me right now) I'm extremely anxious, and I can't sleep, despite having barely any sleep over the last few days. I'm exhausted. Where I hit my head is extremely tender. The wind barely brushing my hair is enough to make me want to cry. I can't afford to go to the doctor, but I'm so tired of being in pain. Previous doctors have been no help. No pain medicine makes the pain stop. Someone please help me. I'm getting in trouble at work because I can't keep up with everyone else.
