Insomnia or?

Something seems off, mentally. I spent the majority of the day with my brain racing, I couldn't stay focused on anything. With the exception of art, then when I stared in on a project I didn't stop until I was completely done, and now it's 3am. I have to work in the morning, I'll be forced away in less then 4 hours now. This type of thing doesn't happen often to me, though it has happened now enough times that I have to wonder if something is wrong with me.

I was driving and could barely keep my eyes focused on the road my mind was just jumping around too much, eye darting. The last time I remember this happening, I went on a sleepless binge of art-drawing for about 38 hours. I'm glad I at least recognized that it was happening again and thus I've stopped for now well at least long enough to try and sleep, but even when I try that it's difficult as my mind is still keeping me up with rapid-fire thinking. I can't even remember half the stuff I think about, like it's going too fast for me to process. I wanted to write this down so I could try and organize my thoughts, and keep a record of how I'm feeling as it happens. I also felt tired, ache and had a massive migraine all day despite taking some excedrin to try and dull the pain. I should probably talk to a doctor about it.
