HELP ME!! Please!!

Okay. So um. I'm 15 years old and I had a seizure in one of my classes back in Novemember. It started in my arms and eventually spred throughout my entire body. I was lucky enough to have a friend in the class who kept everyone else away from me and helped me out. I didn't tell anyone outside of my friend and I never had another seizure. Until a month ago when I was getting ready for bed when I fell down and expierianced another one. I passed out afterwords and woke up an hour later confused, sleepy, and feeling like I had been run over. The next day I talked to one of my friends (who has had epilepsy for a little over two years now) and she freaked out and asked me how long it had lasted, I told her that I wasn't sure and she encouraged me to talk to my mother about it. I told her I would but a month later I still haven't. Someone please help me. I don't know whats going on and i'm afriad to tell my parents because I don't want to cause any problems or bother them. These are become a constant part of my life. I have seizures almost daily now and I notice a weird feeling when I get extremely angry or sad and i've taught myself how to fight that feeling but sometimes it doesn't always work. I notice I have them more if the day has been particularly stressful. But most of the time I have them. I'm learning to recognize them before the come on (my arms or legs will start spasming uncontrollably). Sometimes I'm concious throughout them and other times I blackout completely. I've been told that this could kill me. Yet i'm to afriad [[more like to stubborn]] to ask for help. To tell my mom or to go to a doctor. Because I know my mom will blow it way out of proportion and freak out. Which is exactly what I don't want. I'm extremely afraid though. Can one of you help me??? Do you know whats going on with me? And what I could possibly do?? PLEASE, ANY HELP AT ALL WOULD BE GREATLY APPRECIATED!!!! Thank you..
