Pregnant and epileptic.

I was diagnose epileptic a few years ago but it hasn't really affected me in the past 2 years. When I told my doctors they told me I should keep on top of it because pregnancy has a tendency to bring out past medical issues, but since I usually felt my seizures coming on hours before hand, I ignored it. A few days ago I was experiencing pretty horrible anxiety and was basically feeling crazy. I felt out of control and just all over the place emotionally. Even my coworkers said I was acting not quite myself. But yesterday morning I woke up with a huge lump on the back of my head and my room in chaos. I have no recollection of what took place or that night. I get pretty freaked out when I have complete memory loss as I'm sure anyone would. Anyone else having this? Was there something you did to help it? At first I was relived as I now know I'm not just crazy, but I realized... Crap... That could happen again...
