I think it's because "getting over" is a really long process for someone with severe trauma. And it's often better to inform people around you about the problems you are having and the source of them. Like I have problems with particular task not because I do not respect you or I don't care about it but I am still fighting with me demons. Sure you can not care about that but it's still better that you know about it.
