...Feeling uncomfortable in crowds is also a type of social anxiety....
I read somewhere that people in certain blood groups should best work from home and I'm in that group. It's never comfortable being far from my abode, when living in the city.
While working for the government, I worked on the streets often but now I notice my blood pressure rises when I'm in the streets.
When driving in Lagos, it's like the streets are hostile so when you finally get home you let out a sigh of relief and say a prayer of thanksgiving to God for bringing you back safely.
Riding a motorbike makes you feel much freer because you'll be able to escape from traffic holdups easily.
In close company, one can easily become the life of the party (when I used to party).
For me, this is not a self esteem issue but one of security.
