Dient and Exercise for a 6-Pack?

I am a 16 year old male who is 5’2. I weight 118.8. I was wondering if someone had a great diet and exercise plan for a 6 pack. I workout about 5 times a week, in which I run for 30 minutes at a 6 mph pace. I also swim for about 20 minutes, and do Ab exercises such as crunches, hammer strength crunches, and a couple of other exercises for about 30 minutes. I eat a lot of junk food, I THINK that may be the main problem. Can someone send me a a diet plan with what exactly to eat at each meal. Perferably not too much fish as it is hard for me to come by. I would also like a workout plan. Thanks
By the way, for some reason my stomach never goes away now. I always wake up with a bloated stomach, and even after eating the smallest amount, my stomach stays bloated. I think my metabolism may have slowed down, but really I have no idea. Please take this into consideration.
ALSO! What time should I work out. I usually work out in the morning, but would it be better to work at night to burn off the extra calories?
