I'm not sure how your state does name changes exactly, does it go through Probate? And if so, does it go by districts depending on your area of residence?
I have my hearing soon too, and while I am not anticipating anything to go wrong, I have a letter from my therapist to present to the judge in the unlikely event it is necessary. Coming as prepared as possible will hopefully help your case in front of the judge, who which should *not* be denying your name change for just personal bias reasons.
Worst case, if it is divided by districts and judges in each one, could you move in the future and reapply?
