My brain is under some sort of attack right now - some sort of hyper overdrive of intrusive thoughts

This feels like absolute insanity.

Even as I type, the brain is firing more things at me within seconds - multi-thinking to the MAX - between 20-50 completely different unrelated ideas passing every single minute. This has been going on for HOURS. My thought process is just like a highway of ideas right now, barely have a second to even grasp them before it switches.

Anyone ever have this? What the hell is happening to me. I've had this once before but it didn't last as long and I don't know how it stopped.....
