I'm really sorry to hear this, Krista. I've worked for crazy people, too, and I know how tough it is. You try and try to understand them, and to figure out how to satisfy them. But (as my gf says) you can't use the logic wrench on the crazy bolt. It just won't work.
I truly hope that things will improve for you. You deserve a job that makes you feel competent, productive and satisfied.
