I think that's good advice, but I also do think I'm missing something. For some reason I am just not at ease around others, and I don't get it. I think I lack a sense of self, there's always a need for confirmation from others, not that you would think so if you knew me.
Essentially, there is something missing and I feel disconnected from others. I cannot engage them on an intuitive level, I engage them on an analytical level which tries to look natural, because my intuition is not normal, i.e. doesn't sync with most people. I think this is true for many introverts, and is why they tend to be exhausted by social interaction.
