Thats a very good insight. You FEEL like that, but feelings are NOT FACTS. You may feel like that because thats how you were treated in your family. But your classmates (or whoever) dont KNOW how you were raised. They might be able to sense how you feel, just as anyone can sense what emotion an actor is projecting on a movie screen, for example, by their body movements or facial expressions.

My dad always used to tell me, "Smile - and the world smiles with you; cry - and you cry alone." So - try smiling, not cringing.
