Boyfriend has epilepsy

Hi everyone. I'm here seeking some advice on how to help my boyfriend deal with epilepsy. He was diagnosed when he was about 8, he is now 25. The thing is that ever since he was diagnosed he kind of gave up. He has been very open to me about how he feels and this is what he has shared with me: He has given up because the doctor told him there is nothing to do about it, there is no cure, and so he has to live with this condition for the rest of his life. Therefore, he has this attitude towards it that leads him to forget his meds, to not take care of himself, to follow a non-healthy diet... He has been very sincere to me about how awful it is not to have control over his body, he is also ashamed to tell friends and coworkers he has epilepsy. He feels like it makes him less valuable and less worthy. He also misses Doctors appointments, he used to go to the doctor back where he used to live, but ever since he moved to another city he has no doctor and he refuses to go because "there is nothing the doctor can do for him." I've found this website to be very helpful, but I feel like I need to do more. I am seeking advice on how to help him effectively and how to inspire him to live a fulfilled life despite having epilepsy. What arguments can I use to get him to the doctor? PS: His seizures are not that often, I haven't witnessed one, but I know it really affects him both physically and emotionally whenever they do happen.
