Memory Loss? Brain Fog? Split Second Mind buffering?

I was diagnosed with epilepsy 3 years ago at the age of 20. I am currently Taking 300 mg of Lamictal (generic) during the day and 250mg at night. Recently Ive been having issues concentrating and maintaining focus on certain things or when there are multiple things going on in my mind. It's almost like for a very very split second there is just a glitch in the system, everything kinda like "jolts" (im not sure how to describe it) and I have to take another split second to reassess what I am doing. Ive noticed these "jolts" or "glitches" prior to having seizures before, but they do not always indicate them... However recently they've been getting worse and worse and freaking me out to the point where I don't want to do anything or go anywhere where I might fall and hurt myself if it DOES end up being an aura-type thing... Another issue I've been having is completing thoughts and sentences.. For instance I'll be telling a story and know exactly what I'm trying to get at when I start, but then I have to take a minute and be like "oh uh... hold on" and try and figure out what I was trying to say... This has also happened to me prior to a seizure, but again doesn't always PREDICT one coming on. Also I've noticed that when people talk to me sometimes it takes me a while to process what they're saying or asking. For instance, my boyfriend asked me how my head was doing (referring to the topic here) and I said "oh good!!" because for whatever reason i thought he was asking if i had a headache.. but then realized what he was actually asking and got embarassed... My mother also told me something and I wasn't really able to grasp what it was that she was talking about until a few sentences into the conversation... I feel like I'm losing my mind. I havent been able to find anything that remotely sounds like what I'm going thru online and it's really starting to bother and freak me out. I start questioning myself and testing my mind because sometimes it really does feel like im losing my intelligence, my sharpness, my wit.. and its frightening, especially only being 23 years old... If someone could PLEASE help, or at least tell me they can relate I'd appreciate it so much... I'm starting to really worry that it might start impacting my social and work life.
