Social anxiety is more of being anxious and prone to having a panic attack more than someone with avpd.

I remember there was a kid in my school that would walk up to me and my friends, talking etc.. He would walk up (shaking violently) and when his anxiety gets too much, he would walk away. I didn't say anything bad it's just when his anxiety gets too high, he would have to leave I guess. He would always have his hands together, fidgeting when walking through the hallways and stuff.

For me (with avpd), I get anxious when a car drives towards me. Especially if it's driving slow. I'm capable of having a conversation etc.. But I just try to avoid it. If a friend asks to go to a party or do something, I say no.. Because.. I don't even know sometimes.

Some People with social anxiety can't leave there house because they're afraid that someone will see them and the anxiety would cause them to go back inside.

For me, I avoid going outside because I would fear confronting someone and in my head, that person would be judging me. I get anxious while waiting for judgment and when the judgment happens, I feel sad and defeated, and say "I should have stayed inside. I'm never going outside again"..
