Eating disorder seriousness?

i try not to eat anything but if i do i need to throw it up.. like yesterday i had 2 biscuits and couldnt deal with it, and today i had half a bowl of bran flakes and i had to throw it up.. does this mean im not taking it seriously enough for it to be serious? so i dont really have a serious problem cos i still bring myself to eat soemthingi n the first place?
