Well, I think compared to many people on this site my SA is pretty mild.. I can talk to people etc especially if I'm feeling good/my energy is high..
It used to be much worse when I was a teenager, I really didn't know how to talk to people and was very alone (even when around people).. So I know it CAN get better, for all of you out there!!
Now, trouble is the mood swings and the more demanding situations.. Like not your everyday stuff.. If I was feeling bad, I might just want to stay in my room lol.. (or online)
I've been also afraid to call some people on the phone or do certain things that might be important. I've had trouble sleeping before certain events, cause I was afraid what might happen, and usually it all went sorta well.. It was still anxiety-provoking before.. And I had to make myself do it (or Mum did lol).
I have trouble talking to goodlooking guys

and a phobia of dating, lol. And of politicians and people in authority and such. Or people that I might be angry with.. Or people that are important to success of some projects.. (Maybe I ascribe too much importance to them and overthink stuff? Many people here seem to do that..) If I know people informally and have talked to them about other stuff before, it's way easier..
