Migraines :: What Are Common Symptoms?

I'm only 23, but I hope someone will take me seriously.

I've had a constant headache for about four weeks. It kind of fades in and out, but is still always there. I've had streaking pains in my head for about a year. There is also a spot on top of my head that sometimes feels like someone is drilling a hole in it, and I sometimes get this with the headaches. The top of my head is sensitive to the touch in some spots.

Also, I've had stomach problems for about two years now, and the doctors can't figure out what it is. I've had just about every test done, and everything says I'm fine. But I get nauseated and sometimes throw up after every time I eat, and sometimes when I just smell something bad or think something is going to taste bad.

I also have a very bad short-term memory and dizziness. I also can't keep my balance a lot. I've noticed some changes in my personality/thinking patterns. I keep thinking it's my bipolar disorder, though my psychiatrist is not sure I even have that. Anyway, I get very paranoid, I'm very obsessive and impulsive. I also have this thing with my speech where I sound like I'm dyslexic, but I've never had that until all these other things started happening. Oh, and I've had episodes of non-stop emotion/incessant crying and episodes of no emotion whatsoever.

The question I have is does any of this sound like something you're going through or symptoms?
