Boyfriend with Seizures

So, I'm not sure what to do and need advice. A bit about the circumstances: My boyfriend has brain damage, and has had it since he was young. We've been dating for about two and a half years now, and a few months into our relationship he had his first seizure, and has had them periodically since then (once a month or so, sometimes more, but always at night). It turns out he may have been having them for a while-as his previous roommate later told us they often heard him thrashing about and things. It took until recently for him to finally go to see a doctor about it and, as I suspected, they diagnosed him as having a seizure disorder. Unfortunately, he has other problems due to the brain damage so he was always against going to the doctor about it and had convinced himself it was just a weird form of sleep walking. The first problem is this: He, justifiably, isn't taking it well. He's extremely angry about it, angry at the doctors for diagnosing him, angry that his license is getting revoked, etc. So far he's only had seizures at night and pretty much thinks the doctors are over reacting because they "think" he might have seizures during the day sometime. At which point he flat out said he'd kill himself instead of having his freedom taken away. I don't know if he would actually do this or not. We've discussed it and he's told me he can't promise me he won't, but he'll think about it. Which is probably the best I can hope for with his current mood. Thankfully he's limiting his car use and is letting me drive him to work on the days I'm home when he is, since his license has been revoked and we can't afford the extra tickets he could get. At least for now. He only works a few minutes from where we live, and I've never seen kids running around, and the only people that I really see on that street are the other factory workers (who really only use the street for about ten minutes as they come and go to work) so if for some reason his seizures DO end up happening during the day his chances of hurting someone other than himself are limited. Other than working he mostly stays at home playing video games, which have never triggered anything other than typical video game related behavior. The second problem is he absolutely refuses to take medication. He was on medication when he was younger that had similar side effects to seizure medication (mood stabilizing drugs) that pretty much turned him into a "zombie" (as he put it). So he won't take it at all. I can certainty understand why he won't take it. It was my fault that he went in for the tests, and it was me taking the video of his seizure for his doctor. He's made snappy comments about how he won't ever go to the neurologist again because they always **** him over. Angrily ranted about how he doesn't care what the DMV says. I just don't know what to do. I want to help and support him, but I don't know how to work with all of his anger and resentment towards the situation without making it worse. Does anyone else have experience with a loved one in a similar situation? Any experience with nocturnal seizures? I've pretty much been the only one of us researching and trying to prepare for things, but I keep seeming to find the same two articles about nocturnal seizures and feel woefully under-prepared.
