I get anxious when riding in unfamiliar places, even if I am with people, and the riding is not challenging. I like to know "where" I am and am not one to just "explore." Well, I might be OK with that in my local area, but generally, I need to do a ride once before I am OK. My sense of direction is pretty good, but it's like I have a need to "feel" where I am. It sounds weird and I am pretty sure it's a mild form of agoraphobia. I am the same if I am in an unfamiliar place on foot. I do travel, though and now I know to just ignore it and eventually I feel fine. For a long time, I would just be in a bad mood and snappy in the beginning of a ride, mostly with my friends or my DH (not on bigger group rides) until they figured out to just leave me alone until I got over it. So now I just keep it to myself and meditate if I feel anxious.
