When another person is too obviously closely listening and watching me and I'm not sure about their intentions, i feel sometimes threatened by their presence and it has such a powerful negative effect on me.

I may become instantly from a charmer, natural and confident person to an anxious and self conscious. Like I'm ashamed of something. I'm listening in real time to my own words as a third person, observing lf from outside, and no longer present with the person I want to be with but in the mind of some random jealous stranger or over protective friend.

Ant advice on this please or just what you do? Avoiding approaches until you feel it's safe or just don't give a damn (how?!?)
