I get what you're saying, and I doubt that we're going to be able to convince you otherwise, but I REALLY don't think you're about to fall into major epilepsy (like really, really don't think). Anxiety can take on a whole spectrum of symptoms, it's not always just, "pain, rapid heartbeat and panic attacks." Plus, it's largely subconscious, so even though your attacks last only 30 seconds, it could just be how your overactive stress hormones are choosing to manifest themselves in the moment. Believe me, I'm not trying to diminish what you're going through; anxiety is not a throw-away diagnosis, it's serious stuff.
Also, do yourself a favor and get off those epilepsy boards! Reading them is NOT helping, trust me.
Maybe right now a "wait and see" approach is best. If you develop epilepsy, you'll know. But if you don't in a reasonable amount of time, maybe then look into other options.
