From what has been said here I conclude I'm an introvert too. I don't like people, I usually want to be left alone. I still enjoy being around my friends, though. Generally around people I like I can be really extroverted, but when I'm forced to attend some social event where I don't know 80% of the people there, I just go "sit in the corner". On the other hand I have some SA symptoms too, like, for instance, being afraid of starting a conversation because I suck at it, and thinking that the person doesn't want to talk with me anyway. Also, I tend to avoid having to walk with my
friends over long distances(half a mile+) even though I can often keep the convo flowing. I always fear that I will have nothing to say, or that I'll have to talk about stuff I'm not interested in. Also, it drains my energy, unless I really enjoy the conversation, which is not as often as I'd like to. Now I think that I stand before a decision - I can either try hard and be a normal person or I can shut myself in the house and over time develop SA. Sorry for the long post
