Weird Headaches Please Help Me!

Hi, I was diagnosed with Epilepsy when I 13 or 14 and, every since then I have been having seizures (and before I was diagnosed). Well, in October of last year I had a seizure and I fell out on the cement and hit my head. No, it didn't bleed but, it hurt really bad. I asked the doctor about it and he said it was fine and the pain will go away. So, I never thought much about it until now. I started taking my medicine off and on. And, yesterday I was feeling very weird--it felt like my hand was shaking. I woke up before then and took medicine, Levitracem, I think that's how you spell it. I start looking up research about it and some articles said that if I don't get enough sleep that it could cause another seizure and, I haven't been getting enough for an 16 yr. teen. I find myself staying up to 8pm-8 something in the morning. Today, my head started hurting from where I hit my head and it just felt like in different spots it would hurt. I usually get shivers in my feet and legs and sometimes when I sleep I feel like my eyes are twitching and I'll wake up and feel the same and go back to sleep only to face the same thing sometimes. I just need to know if I should go talk to a doctor and whats going on with me. I don't want to have another one, I find myself paranoid and scared at times and I don't know why. Like, I'm scared somebody's going to come in the room in kill me or, when I'm in the shower. Please help me, I feel like I'm going crazy.
