This is a cool concept, I never really thought of applying the stages of grief to having a mental illness, but it fits very well.

I spend a lot of time in denial: "I only acted like this because of x, y, and z, not because I have bipolar disorder," and "it can't be BP because the doctor that first diagnosed me was stupid and all the others that diagnosed me after were just going based off of incorrect and biased history." Right now I'm at acceptance.
