It is like that to me. I believe that I've just learned the proper motions for some interactions, and I can look to be very social person proficient in communications. It is easy for me, no problem. Till I hit some situation where I need to think fast, trying to figure out what is expected of me now.

> I am absolutely terrified in near all social situations

It is different for me, I'm absolutely confident in near all social situations, but there is a catch, I actively avoid social situations which make me terrified, and I'm pretty good at it.

> I have zero idea how to make small talk with people I haven't known for years.

I have never bothered to get the idea of a small talk. I hate it from my teens, I hate to dig in my mind for something I can say when there is nothing to say. Or to voice opinions about things I don't care (and "i don't care about your TV-series, I never watch them" doesn't count as a socially acceptable opinion). So I just avoid such situations overall. Generally if you avoid talking with people tet-a-tete you don't need to talk small. You can just look like you are listening, why calculating ways to leave the place without offending anyone.
