Significant other of someone with epilepsy

Hello, As you can probably tell by the title I myself don't have epilepsy but my girlfriend does and the last couple of years have been difficult to say the least. She won't have a seizure for a month or a month and a half and then all of a sudden they'll come back and she'll have them in clusters of about 3-5 spread out over about a week. The past two seizure clusters have brought on postictal psychosis which has been very hard to deal with for her, her family, and myself. She didn't have seizures for years but for some reason they came back in 2014 but they were very spread out, maybe every couple of months or so. It seems like when she got on meds is when they started becoming more frequent. Is this common? She was on Keppra for several months but is now on Zonegran which doesn't seem to be doing anything. Her current doctor is at the University of Chicago which is supposed to be a leading facility in Neurology but I'm not impressed. I understand there is no cure for epilepsy but her doctor doesn't seem very involved. Anyway, I am sorry this is so long but I just wanted to see if anyone can offer up any advice or helpful tips. I know this is really starting to get to my girlfriend and it's causing her to be depressed and I want to help her any way I can.
