Talking to new people isn't the problem for me.

Its when I run into someone I know that it starts to kick in.

Or when I'm going to be on a road trip for a few hours with people I kind of sort of know.

Or like on a date.

I feel myself getting anxious and quickly fumbling for things to talk about and just not wanting to come across as weird. Or I want to be more like able.

How do I get over that kind of anxiety?
