Is thought broadcasting when people can actually hear your thought? im pretty sure im not hallucinating it because people repeat them, every one.

No: Thought broadcasting is the *delusion* that one's thoughts are perceived directly by others. A delusion is an idiosyncratic belief firmly held despite strong evidence to the contrary. Since everyday life gives strong evidence that thoughts cannot be perceived directly by others, a firm conviction that they can would be thought broadcasting, a delusion. "pretty sure" doesn't count.

Yes: Yes that is thought broadcasting, when you feel people can read your mind, hear your thoughts or penetrate into your secrets. This problem is treatable and you can get huge relief and comfort by seeing a doctor.
