A moment were you had the false impression you were close to death.
For me:
-Panick attack. I had a stressful internship, and one day, it materialized with a panick attack. Suddenly, i was increasingly paralysed, my skin became insensitive, had heavy tinglings, had hard to breath. I though “that’s it, i’m about to die” and managed to call the ambulance. Of course, by the time it arrives, the crisis had stopped, but i went to hospital anyway. This is were i learned that it was a panick attack, and that was not a vital emergency. If you don’t know what it is, you’re really convinced you’re dying.
-When i tried a blood donation. My blood pressure lowered rapidly, i became weaker and weaker and feeling increasingly bad, they had to stop the process.
Mine was when my appendix was gangrenous. I’ve never felt that intensity of pain even though I’d been through a lot by that point. Genuinely didn’t think I’d survive, and I guess technically I was pretty close to death.
