I have social anxiety as well, and my main problem is not wanting to be judged. It particularly comes up in employment situations, like looking for work and everything that comes with that, and on-the-job stuff. But it's also meant that I don't have experience with a lot of things like going shopping on my own, hairdressers, making appointments etc.
At the moment, I think I need to do more to try and overcome it.
This is a great topic.
It might sound funny but I don't like going into shops without knowing what to expect. I think I'm worried that I'll end up bothering the salespeople or interrupting someone or something. I like to be able to see into a shop and know what to expect when I step through the doors.
That's proving more difficult here in Canada where shops are designed to resist the cold in winter, so many have closed heavy doors, recessed doorways, and a minimum of window space (to help keep the heat in).
It's even stranger for me because I worked in retail stores for 12 years. I know what it's like in there and I remember complaining about customers. "This sales job would be so much better if it wasn't for all the darn customers!" 
I think I worry that they'll complain about me, too.
In terms of dealing with social anxiety, I'm reminded of a scene in that recent US TV show 'GIRLS' in which the main character Hannah talks to herself in a mirror before meeting a bunch of old high school classmates: "The worst stuff that you say sounds better than the best stuff that some other people say." (see the attachment below)
Oh yes, I can DEFINITELY relate to everything on this thread.
For me, I worry that people will think I'm stupid or that I look like a 'freak.' I get really self-conscious of my voice (because I worry others will think it's 'stupid', even though I sound perfectly normal) so that makes it harder to talk during conversations. At the moment my anxiety's so bad I haven't actually been able to go to school in months, but my psychologist and I are doing CBT and she wants me to start exposure therapy. Things like going into shops and appointments and talking on the phone are really hard, as well as talking to people I don't know. It's a horrible thing to have to deal with on a daily basis, but I'm confident I will get better though - I just have to keep trying.
But the really ironic thing is that I'm basically fine with public speaking. I was on the school debating team (& won 'best speaker' award quite a few times 
) and I got up and spoke at my Grandpa's funeral on my own where there was like 100 people... I can speak in front of one hundred people without breaking a sweat but as soon as I have to make conversation with just one or two people I completely freak out...
