Why do I fear big crowds of people? People have said it’s claustrophobia. But I know that I’m not claustrophobic because it’s not being in a small space or being traps that scars me. What could it be?

I think you may be feeling vulnerable or lost. I remember when I was in the middle of a street in a big city and crowds of people moved past me quickly. I felt so overwhelmed and lost because I couldn't see anything in front of me and I was also scared that people were looking at me and judging me. What I usually do then is I just walk ahead, not caring what others may be thinking of me because I was never gonna see them again. I breathed, I looked at a map of where I was, collected my thoughts and walked straightforward without looking at anyone.
