I tend to be quiet. I often have no idea of what people think about it. Some ask me why I am so quiet. I am content. Others are happy to have the spotlight!
Please don't assume people are thinking negative things about you. This is more about your fear of what they may be thinking. Your fears about this may be reflective of low self-esteem?
Maybe list the things you like about yourself?
In time, work on learning to love yourself!
