Could it be Epilepsy?

I'm a 16 year old female, not particularly worried about my health, just curious as to what my symptoms could be! When I was about 6 years old, I cracked my head open on one of those bumpy slides at a fairground (a little boy ran up it the wrong way and knocked me backwards) I remember it vividly, when I arrived at the bottom of the slide my Grandma, who I was with for the day, scooped me up when she realised I'd seriously hurt myself, and I just remember seeing my blood all over her neck and arms. I was rushed to the First Aid area where the first aiders bandaged my head up whilst we waited for the ambulance arrived. I had stopped crying almost minutes after the accident and all they did when I got to the hospital was glue the small hole in my head back together, so I'm guessing it wasn't a very serious injury. However that night, and almost every night for the following couple of weeks, I had what me and my family call "panick attacks", where I'd get up in the middle of the night, crying and screaming for 'Mummy and Daddy', running around the house for no particular reason, and generally acting panicked. These episodes lasted around 20 mins (I think..) and then I'd wake up and wonder what I was doing out of bed. As time went on, these episodes got less and less frequent, and as I got older they got less servere. Up until about the age of 11, I'd typically have 1-2 a year. From the age of 11 to about 15, I'd be awake whilst having the "panick attack", but still have to go into my parents to help me calm down and feel better. I'd have an overwhelming sense of someone or something telling me to do something I did not want to do, or couldn't do, and it scared me a lot. I know this doesn't really make much sense but it's the only way I can describe it. A few weeks ago I had my first episode that I was able to control myself, without needing my parents to calm me down. I woke up during the night feeling sick and scared, but managed to supress the horrible feeling that accompanied it and went back to sleep. These episodes can occur any night, but I usually get them when I have had a lack of sleep or if I have a high temperature. Oh, and I also associate the overwhelming feeling of having too much to do with the colour green :S I have no idea why. My mum seems to think it is a very mild form of Epilepsy, but if anyone else thinks they know what else it could be, please let me know (:
Thanks.
