That's where I was at not so long ago until I realized that if you have no starting data, just copy over some data from your peers :) Look at how others behave socially and start with those bits, it's not going to be easy but it is something to use until you have enough to bootstrap your own thing.

And remember even if it is weird, play along, things get better as you go. Keep making conversation (and always smile), it's better to be the awkward guy trying rather than the weird/silent/alone guy in the corner of the room :)
