What should I do if my doctors refuse to diagnose me with bipolar?

I definitely am bipolar 2 and my Phycyatrist refuses to diagnose me with it because of my autism but I clearly have it. Now it’s gotten worse and I could never have any help without getting a proper diagnosis. I still live with my mom and she don’t think I am bipolar also and won’t allow me to get another opinion because I still live with her. What should I do?
