Struggling with Seizures and Anxiety in a Rigorous School Program

I’m staring an extremely rigorous school program and it’s an hour drive to and from the school every day. My seizures are triggered by lack of sleep and I have severe anxiety that can keep me up at night. I have to wake up around 4 or 5am every day and go to bed at around 6pm every night. I’m so scared that I’m going to have a seizure, because when am I supposed to study? Especially since I’m going to be on the interstate for two hours per day IF a wreck or 5pm traffic doesn’t stop me. And there’s always road work going on too. I’m just so nervous and I don’t think I can make it through the program. I feel so guilty about having seizures and I cry when I think about me possibly having one again. I just don’t see how I’m going to make good grades and get enough sleep. I already take 10mg of melatonin. Any advice?
