I have stopped eating proper meals because when i look in the mirror sometimes i feel fat after a eat, and now i dont feel hungry often anyway, and quite often dont eat anything until teatime. Sometimes i feel too full so am sick.I havent told my mum and really dont want too, i have told a teacher and close friends. I have missed my period, im worried they irregular. Should i go to a doctor, i am too scared to go as i dont know what i would say when i get there. Please help, what should i do??
