Am i going to become obese by eating all this cereal, i am recovering from anorexic!?

basically ive been going through cereal like there is no tomorrow and i'm so worried i'm going to become obese and just gain so much weight from it. i normally have in 1 bowl mixed together crunchy nut cornflakes, rice krispies and some special k, but recently have had a lot of granola, like 2 box's within 4 days! i am recovering from anorexia and have gained quite a bit of weight, as i eat dinner and throughout the day but then at night i just crave cereal and will land up eating 2 or 3 mive bowls of it. this is really bad for me isn't it? am i going to become severely overweight by it? i'm scared!
