Okay well that is good to hear! Um actually I have never ever run competitively, in fact I hated running and never knew why people did it. But that was also last year when I was 210lbs... then I got accepted by some miracle of God into a physical education leaders program, but all my peers were a lot more fit than I was and I stood out as the most unfit kid in class. So I started to try to lose weight and hit a snag somewhere around 160-150lb mark (my goal is 130lb.), so I found running and here I am. Never ran competitively in HS, not planning to in college, just for pure sport and exercise. And I guess I'm not using a training program, just trying to run the 5k everyday and get better times is my program I guess.
Ok, wow. Where to start.
First off, don't run the 5k every day. To see any real sustainable improvements you'll have to run further than a 5k at certain paces. You'll also have to run speed workouts as well. What you plan on doing right now is doing it completely wrong. In peak 5k shape for me I had some long runs as far as 8-9 miles. Variance in the workouts is key.
A good place to start is Runnersworld.com Lot's of great resources there. Use the Smartcoach tool. You can pay for it or use the free one over and over again.
Also, this book is fantastic.

It's a 3 day a week running program I swear by. It's mainly for half marathons and marathons but there are 10k and 5k programs in there as well. Also, just a good general book on running as far as diet, training routine, and stretching go.
Get good shoes. What do you run in right now?
You're trying to drop to 130? How tall are you? Is it realistic to get that light?
Honestly, if you're serious about running and you're still in HS....run XC and/or track. You'll learn a ton about running and workouts that way.
