Yes, I believe I unfortunately worry about the worst in people and the only positive in that is that I am aware of it. I dislike talking with people because I find most people to be shallow but if I'm honest with myself I know that I crave getting to know people more.

I too, am not awkward or nervous in social settings either, but if they don't have a definite ending I do find them draining and need time to myself. I too abhor social media - I find it trite and shallow.

I honestly think it's just a type. I found social interactions that suited me like...ones that are surrounding a topic of interest, like a book club or philosophy club...and then talking about that and once the hour is up everyone logs off.

I prefer that type of socializing, and on occasion I have found 1 or 2 people that I manage to socialize with here and there.

I'm not sure its an issue, but if you want to socialize more, maybe you're just not a "going out to a bar and chatting forever" person...or a "let's take a selfie" person.
