I'm anorexic/bulimic, i need to get over this obsession.....?

I don't know if this is normal for anorexic/bullimics. But i am obsessed with food! not in the normal anorexic way e.g. counting calories (although i've done all that). But i'll walk around a supermarket and go down the isle with all the chocolate, cakes, pizza etc. and just stare at it, and feel it, look at the calories and fat content..I get some really bad looks of people. I'll also go on youtube and spend hours watching videos of people eating food! i'll search 'Eating contest' and watch people stuffing their faces with pizza, burritos, burgers..I get pleasure out of it. Is this normal?
