Okay, guys, hope this wasn't a private conversation because I've got a beserk 6yo too...it's soooo nice to hear I'm not alone.
I remember reading years ago that age 6 is alot like age 2, except that it's worse because the kids are bigger/louder/etc. I think this may have been in the Luvmoor's book (which I can't remember the title of, but it had gobs of stuff about development and how kids get really weird right before a new intellectual and emotional breakthrough -- they called it a "hesitation" before the child plunges ahead). Dd was a delightful 2yo, so this seems to be payback time for how easy we had it with her 4years ago. Plus we now have a 2yo who is VERY typical. So we're getting it in stereo.
A mom with 4 kids ages 10-20 commented that whenever her kids got really crazy she would check their mouths and almost invariably find new teeth coming in. Her theory was that fussy teething isn't just for babies. I thought it was interesting because R. Steiner made a big deal of the change of teeth in the Waldorf philosophy.
So, right now at our house we're dealing with the holidays (even if you try to keep it lowkey in your own home it's blaring at you whenever you step outside your door, and it's nervewracking for everyone), plus the 1st 2 teeth are out with 1 new one coming in, plus lord knows what else is going through her head.
As far as the crayon thing, that reminds me so much of the Broken Cookie Syndrome, wherein the person falls apart because the last cookie in the box is broken...it's not about the cookie, the cookie is just an excuse to fall apart (an analogy would be that your back doesn't go out because you bent over to pick up a piece of paper; it goes out because it's been going downhill for years, and picking up that piece of paper is the final blow). I found myself re-reading Aletha Soulter's Tears and Tantrums, and also Helping Young Children Flourish. It helped some. Sometimes I hold her and just let her cry. Sometimes we get to laughing hysterically, and that helps too. I figure she has few avenues to disperse her strong emotions, so I try to make space for her and not force her to stuff them down inside. Today, though, I declared myself in timeout and locked myself in a room for 15mins.
I wish I could say that I'm teaching her that, even though I don't LIKE her fits of crabbiness, I love ALL of her, whether she's in a good mood or bad. Unfortunately, I seem to be blowing it on a regular basis.
