Hi Velvette,
Welcome :) I'm fairly new too, but regarding your interest here, I thought I would tell you that for me...I tend to tell everyone my diagnosis. Like I can't keep my mouth shut. But I was only recently diagnosed. My husband knows everything, but my son is only 5, so he only knows that "something very bad happened to mommy when she was a kid and that's why shes sad a lot" or "sick" or "crying" etc. I'm sure as he gets older we will explain more, but not now. My mother also has ptsd, and had it as I was growing up, although it wasn't diagnosed until recent years. I feel really bad for my son because I can tell that he is aware that I am not doing my job as a parent. :(
