How do i stay motivated with going on a diet?

I always feel fat, but at the end of the day, I end up overeating. How can I stay motivated? I feel embarrassed about going on a diet, so is there any way without having a diet buddy?

just think about it... if u exersize all day then pig out, no worth exersizing, dont eat that much and run a lot.

here's what i think would work:

Buy something(a pair of pants/top/swim suit) that you like...but buy it too small..
this way you can work to fit into it!!!
hang it somewhere you'll see it daily and let it be a symbol for you to diet.

best luck,
let me know how you do.

p.s. throwing up is NEVER the answer..
just exercise DAILY and always watch what you eat..you'll like the results
