Just my advice, but I learned the hard way, and have seen many others here go through what I did:
Don't accept a depression diagnosis until they have conclusively ruled out bipolar. medications for depression alone send those in biploar into very serious downward spiral much of the time. A medication trial may be needed to see if it is bipolar. Bipolar up cycles can be overlooked or hidden, so it is very imprtant to rule it OUT before ANY other diagnosis is treated. This is becoming the standard for children and adolescent psychiatric care, but it takes docs a lot of time to accept it. It is so much easier t opush the prozac type medications.
2nd point: ODD is RARELY a major diagnosis. it is a pattern of behavior that goes with other mental health issues. If you accept the ODD diagnosis and just work on that you may lose precious years that proper treatment could make much happier.
While your daughter is being evaluated PUSH for a more complete evaluation from a doctor or team of docs you feel comfortable with.
And 3rd (and most important): FOLLOW YOUR GUT INSTINCTS. Most of us have looked back and seen the biggest mistakes we made in parenting our kids happened because we ignored our instincts and followed the so called experts. The experts may know thier field, but we know our kiddoes. We live with them, sweat blood and cry tears over them. Deep down we KNOW if something feels wrong. And that is a clear sign to fight like heck to get something different going, even if the schoool or docs think we are demanding, mean, or off base.
Just my advice. Please feel very free to take what works for you and ignore me on EVERYTHING ELSE. Laughing and pointing, however, should be shared so all can be amused, LOL!!!
