The problem about feeling anxious is that you can resect yourself. From the moment you start feeling anxious the only path available is to feel more anxious, unless you stop doing what makes you feel like this.

Even if I recognize I have no reason to be anxious while talking to someone else, when I feel like this I can't have a proper conversation and give answears I don't feel embarassed about, so I become more and more self aware and every single word I say trying to look normal is an extremely hard task.
