Social anxiety from what I have read about the diagnosis can be related to specific symptoms such as extreme fear of public speaking or fear of most social situations. My experience of symptoms includes extreme fear of public speaking, meeting new people, eating in front of others especially if don’t know them well, and often talking or speaking up at meetings with more than 5 people present. There are more symptoms to include eating alone, but if it’s a quiet corner in a coffee shop I’m ok.
