Having big pimples

As what I have written in my previous post,I was supposedly on a diet but this week I was tempted again to eat some fatty foods.I really couldn't resist the temptation.With the oily foods I eat,I notice that I have some big pimples on my face :( I am afraid that I will have some acne nodules if I continue to eat those oily foods.I do not want to have those!Hope these pimples will disappear coz I do not want to hide my face whenever we go out.
