Lunch hour at work

Everybody eats their full and plenty meals whilst I have to endure hunger.

I shouldn't be hungry because I've eaten what a "normal" amount is...

What do I do? I go to the school library and try to occupy my time with something else. I don't look forward to the stomach grumbles...

Do you eat breakfast? I know that a lot of people trying to lose weight dont eat breakfast or eat the wrong sort of breakfast. Its a big mistake and makes the rest of the day, especially lunchtime so much harder than it should be.
