I just saw a study where a girl diagnosed bipolar had sensitivity to white noise. There was a period where all I would hearis white noise. Constantly in my head. There was no off. MONTHS. It was mixed with static.

It was accompanied by headaches, and I was hypersensitive to cold. Couldn't be in a car with ac, always had on a skull cap. Gp said it was my sinuses. Gave me antibiotics. 

Told my first psychiatist. He sorta brushed it off. 

I was also sensitive to anything loud. Couldn't be near a blender.
