hiya, its only a suggestion but it might not be epelepsy it could be chemical inbalances. I am no way saying that starving yourself is ok but maybe if you try to keep drinking water and take some mineral and vit suppliments it might help with the fitting.
Please try and seak help for it though its so serious.
Only last night i was watching a program on a girl who is in a vegatated state due to an ED which led to a fit. She now can't even sit up or talk or comminuate

Please don't get like that or die, please hang on and seek help
