Unexplained Seizure: Seeking Answers and Support

So the other night around 10 past midnight, I had an "episode" like none I've had before. I'd just been to the toilet (no issues there) but as I was about to get up and sort myself out, my vision just went, like it usually does but I didn't get any dejavu or weird feeling this time. I managed to guide myself along the bath and to the door, grabbed the door handle and I mean my hand gripped it hard. My vision was still messed up and it was like I was subconsciously trying to fight whatever it was, my head went up and down up and down several times and then I blacked out and went down unconscious. Idk if I seized because nobody was awake to see it. I came around and stumbled to the bedroom covered in sweat, head felt heavy and my hearing had gone all fizzy? Kinda sounded like a radio out of tune? Then the fatigue hit me like it does during my usual seizures. Can someone please shed some light on what they think happened? My bf rang my neuros secretary over a week ago (the day after it happened) and I still haven't heard from them. I've even made my local gp aware of the event. I feel very stuck, confused and ignored.
