Accepting my seizure disorder. Questions about memory loss.

Hello everyone. My name is Kim. I'm in my forties and I have had migraines since I was a child. I would come in from playing in the snow and the contrast from bright to dark would set them off. I had a grand mal seizure my first year in college just riding in a friend's car going to lunch.... Have had maybe two more grand mals in my life and then I think I switched to partial seizures. I've continued to get migraines also and some that I thought were partials could have been severe migraines or vice versa. They've been pretty well controlled with meds I guess? Or maybe not if the migraines were mild seizures? , Since I thought I wasn't having a lot, may have been lax on always 100 percent taking both my day and night doses of tegretol. I hate to admit I need it. I won't be making that mistake anymore. Saturday I went to a nieces graduation party (no alcohol was consumed, I do not drink) and on the way home I started feeling funny and had to pull off the highway. My daughter was with me and I do remember her telling me I was not alright to drive. What upsets me the most is that I now have no memory of the party, the day before the party, and part of the previous week is a little foggy. My logical thinking has also been a little off this week and I'm looking at clothes I bought when we went shopping and not remembering buying them even though my best friend sent me a pic I sent her when trying stuff on and I look at pics from the party and remember a little snippet. Looking at bank deposits not knowing what the money was meant for. I have to say this seizure has affected me more than any other. I can't stand the thought of losing memories. And my brain has always been my thing. I've always been the smart girl or the funny girl. Quick with a story or imitation. I have a busy job where people rely on me for their safety. I've never had a seizure affect me like this before. Usually I snap out of it pretty quick or if I can't communicate I still can tell what's going on. I did tell my neurologist and we are scheduling some tests. My seizures/migraines do come around my period and I think I'm hitting perimenopause because this one took a month and a half to come so I don't know if the hormones have an added effect or what I should do about that. I'm just scared. My daughter is scared for me now too I think.
