Sorry, but you are wrong. I have big time problems with social anxiety and I do have friends and a job. However, I am a good actress and I don't let on about how awful I am feeling when in a social situation like a party or work happy hour. I am a complete disaster when it comes to dating and any sort of a serious relationship. If someone can't hold down a job and they are a total shut-in avoiding the outside world because they fear judgment by other people 24/7, then that is severe social anxiety. Not just run-of-the-mill.
