People of Reddit, When is one time you have felt genuine, 100% fear?

This one is easy: the time my brother had his first epileptic fit. I was in my early-twenties and my brother is five years younger than me. One night I was in my room on my computer (still lived at home) and my brother falls through my door and nearly hits his head on the desk. He seems shaky when getting up and a little confused but I put it down to sleepwalking - which we both did, often - and keep an eye on him while he walks to the toilet. My mum calls me through and asks what the noise was. I tell her what happened and we have a little chat while my brother finishes on the toilet, walks back into his room and closes the door to go bed. Suddenly there's this huge bang and me, my mum and stepdad rush into the room to find my brother having a seizure on the floor - arms and legs twitching. Except for being born with a hole in his heart and a collapsed lung he has never had any health problems.

When I look down at him fitting my first thought is, when this seizure stops he is going to die. I don't know why I thought this, I was just scared out of my mind. I'm good with stressful situations but this is the first, and last, time I've completely froze. It didn't seem to twig straight away that we need to ring for an ambulance - probably shock by all of us, it must have only been a minute, two at most. The paramedics come in and are fantastic, as all British paramedics usually are, ask the usual questions and I shakily tell them everything, and I mean everything, worried that missing something will mean he dies. He goes off to hospital - it's probably 11pm - and I'm wired. There's no way I can go to sleep so I start cleaning. An hour or two later my mum calls me and says they think he's had an epileptic seizure. He's okay. I, completely drained, collapse into bed and I'm being relieved - scared but relieved.

He's good now. This is probably six years ago. He had another seizure 6 months later but because we knew what it was we weren't nearly as scared that time. I think he had one more seizure six months after the second one. He went through a couple of different medications in the year after the first seizure and hasn't had a seizure since - with the exception of one time where he hit his head and got concussion. The doctor thought it caused a seizure but it was possible that the seizure caused the fall but he was fine anyway.
