It is exactly how I feel when I'm in a mixed state. All I can do is isolate and let it pass. The worst of it is over in about a week (for me), but it is pure hell, isn't it?

I isolate until it is passes. At work, keep a lid on your irritability. That's the symptom most people notice. Combat the confusion by taking your time and forcing yourself to slow down and concentrate on one thing at a time. Take a few days off if you can, and spend them in bed. Call your doc and see if you can get a prn sleeper.

Best wishes and get your anger out here vs screwing up your relationships. You can write a book here, and forget spelling errors. Let it out in a way that doesn't include the people around you.
