Start looking at the people you speak with and listen to what they have to say. This may sound silly, but you’re likely not doing it right now because you focus too much on what you think they think about you. You need to switch that external focus into an internal one, where your thoughts are your own and not filled with trying to read minds. Because I’m guessing that you can’t read minds. So look at people and judge them, with practice you’ll eventually start to forget worrying about what they may be thinking. Hell, you might even notice that you rarely judge people negatively, and if you don’t judge them negatively, then why would they do it to you? Another good trick is to join a group that does public speaking followed by sessions where you review each other. By doing that you’ll learn that no one is as critical of you as you fear. But you should see a therapist, it can take years to overcome social anxiety.
