All the time. My therapist says this is the main cause of me avoiding people and my social anxiety. I put up an act, a fake me if you will to fit in and suit other people. I'm so scared of people thinking something's wrong with me or of my mood swings that I put up a huge wall. I always said I would be a good actor because what I think and what I say are two different things always especially around new people. It tends to make me think My personality is pure fiction. I act this way to protect myself and others or so I think...it's not always a bad thing but can be devastating to my self esteem at times when I overthink it.
