Living with PTSD is like every now and then you randomly find yourself locked in a cage where you can see and hear everyone around you but you can’t feel them, and they keep yelling at you to just get out.
But you can’t get out. You’re trapped by an invisible wall that no one else can see or feel. They can reach in and touch you, but you can’t reach out to touch them.
So from where they stand you just look crazy. And there’s not a thing you can do about it.
