You'll have to be patient. Depakote, and any mood stabilizer, takes eight weeks, at therapeutic levels, to kick in. You can't know if it will work before that. I highly recommend reading "The Bipolar Child" by Dimitri and Janice Papalous. It's a really informative book, and has a good chapter on the medications. Usually stims shouldn't be introduced for six months after stability on a mood stabilizer and even then some bipolar kids can't handle ADHD medications. I posted a few links you may like to read. Although you're probably distraught, it's a good thing to finally get the right diagnosis. I hope it is right and your child improves, but you have to give it time
