For your own peace of mind - you can identify the individuals in your life who's presence and feelings are truly important to you - and you can approach them with some prepared and planned out communication simply relaying that you've become aware that some falsehoods are being spread about you and that they can always and should consult with you if they care about getting to the truth of the matter (as it pertains to you). If you do this you keep the door open for honest & accurate communication and you will have some peace of mind knowing that you've brought this 'issue' to the attention of certain individuals and after extending the option for them to always reach out to you - the ball is now in their court and you've done all you can do on your end. Wash your hands and shift your focus to more important matters...
