wishing I was invisible in public

HI! college student here :) so recently on my walks to class ive been overwhelmed by anxiety. I go to a pretty big school so theres always tons of people around, and when im walking around campus im just overwhelmed with anxiety thinking about how these people are all looking at me and judging me in some way. like all I can think about for the duration of that 10 min walk to history is how every single person is staring at me and judging me. this has never happened before and my anxiety is through the roof. any advice?
