You do not know what people are whispering about, so feeling that they are whispering about you is just a story your head is making up. So, whenever you find yourself thinking those thoughts, try to remind yourself that you have no idea what those people are talking about. It's very hard to banish those kinds of thoughts, but the more you keep telling yourself that it is not facts, but just thoughts in your head, the easier it is to not let them rule you.

Good luck.
