Traumaticed

Hi! I am scared to death after what happened and need to talk to others who has been in this situation! 3 days ago, me and my fiancee arrived at his brother's house for breakfast at 6.45 am. After 2 minutes (we dere still outside), my fiancee suddenly stiffened, and fell. He hit the asfalt really hard, and he didn't make any sound. Then he started shaking. His brother and I ran over to check on him. He had a hole in his head, he was unconcious and he was shaking. He has never had anything like this happen before, so we were totally unprepared. I called 911 while his brother held his head. After 6 minutes, the seizure stopped, but he was still unconcious, and then he stopped befatning! We gave him first aid as told, and the ambulance was on their way, but they spent 15 minutes getting there! After 2 minutes of first aid, he started breathing again, but that felt like for ever, and he was still unconcious. He woke up in the ambulance, but he was scared and confused and he couldn't remember the last 2 hours. We spent the next 24 hours at the hospital, but then he refused to be there any longer... He had several more seizures at the hospital - different kinds - from what I can tell from these pages: the first one was tonic-clonic. Then he had MANY absence seizures, focal onset aware seizures, and myoclonic seizures. He is 34 years old, has never had anything like this, and suddenly has all of this. His heart rate has changed too, and he sometimes suddenly stoppes breathing for a few seconds, and sometimes he is kind of suffocated. Obviously I need to get him back for more tests, but it's obvious it's some form of epilepsy. However, in addition to wanting all the information I can get about this, I am scared to death and I need to talk to someone in my situation (og similar situation). I haven't slept since it happened (3 days) because I can't close my eyes without seeing the image of his lifeless body on the ground, my own hands and all my clotes full of blood, his brother's voice screaming that he isn't breathing, and (at the hospital) my tough, strong, independent, tattoo-covered, grown man crying, while holding my hand tight, saying "please, don't leave, I'm scared and I need you. Can you hold me?" (not that I was going to leave anyway btw). The other reason I can't sleep, is because I feel the need to make sure he is breathing, and that his heart is beating. I lie for hours just listening to his heartbeat and his breathing ... Any advice? I feel like I have a legit reason for this behavior, but I also know that I can't keep doing this. He is sleeping next to me right now. There is no way in hell that I am able to sleep. I know I am walking around like a zombie and that I need to take care of myself aswell, but I can't sleep, I need to hear his heart beating ...
