When I'm in a group of people, new or that I know, I can easily fit in and make people laugh and have a good time arround me. Even with girls I have no issues and flirting and letting my intentions known comes naturally which leads to what I want to happen.

But when I'm by myself in situations such as simply walking to the grocery shop, having a coffee by myself or walking down the street I get self conscious for no reason thinking people look at me or some bullshit (even though im aware its just in my head).

How come I'm very outgoing and at ease in social situations but get anxious walking down the street, it makes no sense to me.
