It's true; anything to do with "mental" health and we're back in the dark ages. I only tell when I think the person is mature enough, understanding enough, and respects me enough. So I develop a friendship and try to gauge how they treat me first. Then I tell. Even then some just don't know ?? No one has information on C - PTSD. The causes are all horrific in their own way, so who wants to even talk about how you became traumatized. It leaves one feeling lonely, yep. Even my very-supportive-and-tries-to-kind-of-understand-spouse leaves me hanging most days when I want to bring the subject up.
