It sounds like you have alot on your plate right now! I'd say the first thing you need to do is get some support. Even if your daughter didn't have epilepsy... Being a 16 year old mother is hard, as you know. I hope for your sake and your baby's that your parents are helping you out.
I actaully don't have epilepsy, my husband does though. So, I know what it's like to be the (for lack of a better word) observer. You will want to protect her from everything, I know.
I really don't have much in the way of advice, excpet to be patient with her. When you get frustrated and tired of dealing with it, just rememeber that she always has to deal with it. She's completely helpless and everything must come from you. That might be one of the harder things to deal with. What about the father? Is he helping you or involved?
