Temporal Lobe Epilepsy... how long do the seizure symptoms last?

My mother was diagnosed years ago with TLE, so I got to see how the seizures eventually worsened from simple partials all the way up to a rare tonic-clonic.

Starting about ten years ago I believe I began developing it as well. Odd episodes where suddenly nothing seems real and I get highly disoriented, sometimes coupled with rage or fear, but not often thankfully. And normally the feeling lasted from just a few minutes up to maybe 20.

Not the last time however, and my own research so far hasn't been particularly helpful. Basically, I think I had two seizures a day apart. The first one was very short. For about 2 minutes everything looked oddly flat and very far away, but that resolved. Last night however, I very suddenly got extremely disoriented and had vertigo/light headedness. And it lasted for at least 4 hours, because that was around the point at which I fell asleep. All today I've still been feeling weird and rather slow and fuzzy and it has me very worried. I'm going to be calling my doctor about it soon, but I'd like some advice from people who know about it... just how long can the symptoms last?
