I have a fear of offices. Why that is?

I walk into an office. I see clean walls and polished doors. The bland color carpet shows no signs of bouncy potential. Usually when I go to offices, I am dress in casual jeans and a shirt. When someone with a nice suit walks past me, I can't help to think that they are thinking, "look at that kid with his jeans, he does not belong here. He's not one of us.". The office smells like rubber. I feel like I am tiny and judged all the time.
