I'm in my early thirties. I think I have had this (both social anxiety and depression) since ever. But I didn't feel it clearly before I came to North America because I was between my family all the time. But the situation has become worse when I came to North America to study. I have inadequacy fitting in in my own country with strangers. Imagine in a foreign country!! Now it's even worse while working. At least while studying I was seeing students when I was at school, now at work, I work in an office alone. I don't think the presence of others would make things much better, but the current situation reinforcing my depression and isolation.
