Hi Doctor, I Am Having A Problem With Reading. When

Hi doctor, I am having a problem with reading. When I read, my breathing is affected. I be like I'm talking through my nose. Breathing rhythm changes with the sound of the word. I also forget most of the content that I read.
If I want to understand something I read, I have to stop breathing. This brings up headache.
I find out that saying what I read/think is better.
