While I see somewhat where you are coming from, I'm not sure I agree. I think there are a lot of people who would be very interested to know more about me and get information about my ideas and feelings, but my social anxiety is preventing them from getting to know me. I'm not really blaming myself that I have social anxiety, but at the same time I don't think that "society" is beating me down to keep me shy.
1. Our culture strongly values both extraversion and assertive non-shyness. 2. Non-shy people will go out of their way to make shyness suck.
Don't put the blame on shy people (including yourself). That's just internalized victim-blaming.
