You're doing great by having her in therapy and sticking with it. It is hard to be consistent, especially with a house full of young children. 8 years old seems very young to be diagnosed as bipolar or ODD. My experience has been that lots of doctors will give you lots of different opinions, so be careful with who and what you believe, especially when it comes to medications. Our most beneficial resources have been parental support groups, so maybe try to find a group like that in your area. Stay strong!
