What should I do next ? Can anyone help me ?

I was a librarian . Yesterday , I was talking with someone in the library . After finished talking , I can see all of the librarian ( about 5 librarian ) looking at us . I feel embared and guilty , and I ran very quickly towards the door . I accidentally knocked a book on the rack beside me when I ran , I just stop down and then continue to ran to the library door . I pushed the library door and went out . I feel everyone might feel shocked for my reaction . I scared they will hate me . I feel so guilty and embared . What should I do when I see one of them the other day ? Do they think I'm going nuts ?
