Idk whats wrong omg

Okay guys so since last year I have struggled with anxiety pretty heavily. I have been really stressing lately and I noticed the past few days when im just sitting or thinking too much I see static in my vision. Its like when its completely dark when I go to bed I see static kind of and its making the anxiety worse making me thing Im seeing it everywhere now when I know im not. It freaks me out but I have been to the doctor and have been told i am healthy and my eyes are fine.
