alone in a sea of people

i have been pondering something for a while, this was something that FMC pointed out in one of our sessions. we were talking and going through how i interact and feel when around others.
i prefer to be alone, i feel safe alone as there is nothing / no one for me to observe and track. where as in crowds i feel under great pressure to keep track over everyone. this presure seems to bring on my anxiety and a need to run away.
According to FMC the norm is the opposite, and i have been trying to comprehend this since we talked.
to me the logic would be safety = alone & danger =crowds. but this isnt the case obviously, i wander why? i know i could put up many arguaments as to why alone is safety but i also know my arguaments for my view points on crowds could be shot down quite easily.

I would like to hear others views an experiences on this, so please if anyone does read this please let me know what you think.
