Is it just me or the people around me try to hide their social anxiety problems from me?

Name: Ritu Date of Birth: 3 December 1998 Place of Birth: Siliguri Time: 6:30 PM. I've seen most of the people around me say it doesn't matter, they have social anxiety, while they go out to each party, talk assertively, and are perfectly comfortable in the public eye. But I fight to even look someone in the eyes or talk in a group. It gets me into this mindset that I'm dramatizing or shattered. Are they misusing the term, or is social anxiety really that distinctive for everyone? I want to know the reason why my experience feels so solitary when everyone else seems to be sporting it as a badge.
