I beg to differ that nobody from the UK has experienced anything like this, I’m Irish, I grew up in NI so technically the U.K. I’ve never been officially diagnosed but I’m absolutely certain I have PTSD from growing up with the British army on our streets, I was absolutely petrified of them. They were also on a “peace keeping” mission that resulted in mass murder of civilians. To this day my heart speeds up when I hear a helicopter in the sky, I know I wouldn’t be able to cope if there was military on the streets again, pretty sure I’d just lose my mind.
