Help - Now I don't know what is wrong with me...

I am having the strangest "migraine" ever.  There is no pain and I haven't taken any med.  My mind feels almost high.  My ability to use words and cope with my life is coming and going.  I don't feel like I'm all there.  It's like I'm only partly connected to my body.  My eyes switch around from intensely focused to a little blurry and everything seems LOUD.  I basically feel like I'm having a migraine, but I'm not.  I've had some allergy symptoms today and its rainy (I often get them on rainy days.)  I'm not nauseous.  I just feel that swoosh swoosh feeling in the sides and top of my brain.
