No one is owed your story.

Reliving your trauma is not a required step in advocacy work, and if organizations ask for you to speak about these things and you feel at all uncomfortable you can say no. Also, remember that you can require people to compensate you for that emotional labour, that does not make you a bad activist. 

Your stories are your own, and you can take time before deciding to share them if you decide to at all.
