Every time I socialize I'm reminded of the gap between me and normal people

I hardly ever socialize, but when I do (mostly colleagues at or outside of work) I realize how wide the gap is between me and them.

They all have lives, they do things, go places, have experiences to share and talk about. I find myself having nothing to say, I feel so boring and weird, like I don't belong.

This gap keeps getting wider as the years go by...
