Is this a (Simple) Partial Seizure?

I've been having, what I like to call my dizzy spells, since I was around 14/15. They're something I never get used to, and practically fear getting whenever I know they're going to happen. They're nearly always the same, and I can never get used to them. I went to the doctor's once to see what they could tell me. They were very vague and said it might be Benign Paroxysmal Positional Vertigo but did not offer any help or treatment. I looked over the symptoms and compared to how I felt every time I had "an episode". They were similar, but somehow I feel they don't fit. The triggers don't fit well, and the feelings I get from them are more complex than what's described for a BPPV episode. I'll describe exactly how I feel for an episode: It’s like the very air changes, how I my brain perceives everything is slightly…edgier. It’s like a static, and my thigh starts to twitch, I can feel a slight tremor rising up in me. My left fingers twitch as well. Soon my whole left arm, then my other arm are shaking slightly, and it goes up. I can’t see properly, everything is blurring or spinning, I can’t tell. My mind is certainly going on the blink. Much like a changing channels on an old dial tv. There’s sounds that aren’t there, either made up sounds or sounds I’ve heard before but not here right now. It feels like a while, but it’s only a couple of seconds. As it finishes, my vision settles, my mind settles, the trembling stops, but my heart is racing. I can’t remember instantly what I was doing before, I get a feeling of jaime vu. I think I was reading a letter. I can’t quite remember who I am either- no wait, I’m me. I was reading this letter, but I’ll have to re-read it so I know what it was about. It’s a bit less than a minute after it’s over but I feel fine now. The air is different. But I can feel it building back up again soon. I’ll know it’ll happen again. And I’ll be helpless to stop it again. I'm conscious, or at least self-aware as it happens, I think I can move. I think I'm falling or moving though, but I'm not. ------- So is this BPPV? Or is this some kind of simple or partial seizure? They recur over the space of 2 days. Sometimes less, sometimes more. It feels like anything can trigger them when I'm on an "edgy dizzy day". Or sometimes they happen out of nowhere. Please help me, it frightens me every time I know they're going to happen. They scare me every time it does happen. And when they've finished I feel upset but so glad it's over. I feel horrible as they happen.
