I have the same problem with many of my emotions- I think this might be a common theme for people with SP, maybe not though. In any case, this problem is addressed in the FAQ at emofree.com. They recommend that you use the basic recipe on any aspect you can think of, with the hope that intuition will help guide you. Of course, doing this is probably much easier with an experienced therapist (by the way, many EFT therapists do therapy over the phone, you can find them on emofree.com).
My method (and I'm just begining to use EFT too, so I'm still experimenting) is to write down all the negative thoughts and emotions I feel during the day when I'm actually in social situations and then to do the basic recipe on them later in the day.
You say you have a fear of being judged. Well, thats a very general issue and it probably has many aspects to it. You can use EFT on general issues, but It'll take longer (up to a month, usually- unless they are too general). The reason some problems are taken care of in minutes by therapists using EFT is because they pick a problem apart and neutralize all its specific aspects. Again this is all explained at the website. So, there are probably aspects behind your general fear of being judged.
