Hey, I just realized I might have social anxiety. At least to the point that overanalyze myself and social situations way too much. You are right though, with friends I can let a conversation just flow. Talk for hours and so on. Hell, I'm fine at work too. As long as I'm in a situation that sort of "forces" you to communicate I do wonderfully.
Problem is outside of that, I assume no one wants to talk or I have nothing to say or it's not really a situation that allows for conversation (like in class). And maybe it's just me, but it seems like it's hard to find people who are actually willing to "converse." That is to say, at times I feel like I tend to do most of the talking and that they're not pulling their conversational weight.
That prodding, questioning sort of conversation is just uncomfortable.
