When will the weight loss begin to show?

Hey, I'm thirteen, 5"4, 140 lbs, and I'm on a diet that I based off another question that I asked. I feel like I'm dying inside because dieting is a goddamn brutal thing to do, but I feel like its working. I feel healthier and I think my stomach has decreased in volume EXTEMELY slightly, but when will the weight loss really start? I'm not talking scale weight, but when will I feel my stomach actually to drop the weight? I'm not going to give up til it does, and todays like the sixth day, so I'm not expecting to wake up and be able to see my ribs, but I'm working really hard and I'm starting to feel restless. Thank you for your time :)
