Why is the author deeply embarrassed the next day in school? Which words show his fear and insecurity?

The author is deeply embarrassed the next day in school because he was still wearing the same dress that he wore to church in the morning and he had no shoes as he had lost them in the fire. He had to borrow some tennis shoes from his. The clothes he was wearing looked weird, he had no books or homework, and even his backpack was gone.
Words used in the lesson that show his fear and insecurity are “outcast and geek”, “like a zombie.”, “wanted to curl up and die”, “Everything felt surreal”, “All the security…had all been ripped away”.
