hey, I'm an 18 year old girl but I understand completely what you mean by 'fight', even from a young age I could not stand to be sick. So as soon as I feel sick that is it I'm up all night pacing around trying to do anything to take my mind off it. This will carry on until one of two things happens, either I will finally be sick after trying to keep it in for so long or I will finally fall asleep from exhaustion. So yes I know how you feel when it comes to this. Also my mum thinks that my phobia of sick started because of a bad experience I had when I was really little but I was too young to remember it so I dunno if she is right.
