Were you working in an area where there is no reasonable expectation of privacy? When did you become aware that your boss was listening to your conversation? Was she in close proximity to you where she could hear what you were saying, but not what the therapist was saying? Were you talking on your employer's phone or on a personal cell phone? Does your company have any policies that could potentially be applicable in this situation? A fair answer to your question depends upon additional facts, possibly including private facts you would not want to disclose on a public forum. In order to obtain the best advice, I think you need to consult with a local attorney specializing in employment law to determine your rights.
