I completely understand how you feel.
I have social anxiety too (and avoidant personality disorder) which is why I never usually initiate a PM with anyone.
I'm only PMing with people who have approached me first... even though there are quite a few members who seem lovely and I'd like to start a chat with.
wow same, I have avoidant personality disorder too. also to be completely honest I also have very little to no interest in connecting with people whatsoever. there was a pont in Mt life where I felt sad about my loneliness but with time, it became more like a choice because I would consciously keep people at a distance. I just don't feel comfortable with human feelings of closeness.
there are members I notice more than others, some I find funny, some I find wise, some I butt-head with.. but overall I've had a pleasant experience with people here on SS. I cannot think of a single member that I dislike.
SS is a good place. and even if I don't any friend here I still feel close to everyone here and am made to feel comfortable with my flaws.
