Do you ever feel like EVERYONE knows you have PTSD? Or when you're having a (brief) rough patch, that everyone can tell?

A few hours ago I was having some panic...I'm better now. My mother called me in the middle of it. I THOUGHT I sounded normal. But then she called back just now and said that she thinks I should take an Ativan because it seemed like I was having a panic attack a few during the last time she called. How the H--- did she know? I didn't say ANYTHING to give it away, and it was a very short conversation.

I find this at other times, too. I think I am doing such a good job hiding the panic/anxiety/PTSD, but then someone says something, and it's like, CRAP, I guess I'm not that good of an actress after all!
