MBTI shows I'm INTJ, so that makes me an introvert, I'm also shy unless I have courage that particular day.

As with all introverts the energy we gain is from thinking as opposed to
gaining in direct interaction.
I've found that I have good-normal days to where I can play in the social arena for a time, but it takes its toll on me. The drain creeps up on me and I'm unable to hold the line. I've changed and I am on edge now - I'm enervated at this point; and I cant find my previous social mode that I was in - I strangely lost it now. The mood has changed dramatically. This can lead to awkwardness. Hence anxiety and a shyness or a
shying away from the danger zone.
