I thought I was the only one that did that. I can catch myself putting on an act for different people. Sometimes I don't like the shy and introvert feeling I have within me so I try to be outgoing no matter how nerve wracking it is.
So I act all jolly, worry-free, happy, playful, etc.
But then... I get anxiety after because now I've fooled people and one day, they will see that I am not that all the time. In fact, I am shy and don't like to speak much. But because of the act, I talk.

It's a lot of pressure. I wish I wasn't so conscious of when I am acting different. I remember the time where I would act different to (teachers, friends, parents, just like ANYONE would) and would not think anything of it. But now, I notice that I am changing my perspective/attitude around people and I feel uneasy and that I'm being unstable. But I still have the need to be liked so it's hard to just be neutral vs. being friendly/outgoing.
