Panic attacks are really awful.

Capt, feeling you're unreal (depersonalization) and feeling your surroundings are unreal (derealization) = you're dissociating.

If you've body memories / being in your body is triggering, it makes sense you don't want to be in your body.

Capt, you feeling unreal is partly because you're traumatised. Capt, you're not sick but you're wounded, if I make sense?

Has T done anything to create a safe space for you where you can feel comfort? It can be imaginary. I've one where T and I are sitting on steps in the warm sun. Having it helps when I'm distressed.
