Hi and welcome.
I'll second what Cord said - you are going to have to make some changes if you want to see results.

I've copied your original posts and will respond to some specific items.
1.) I'm a total couch potato.
The C25k program is great - I'm following it myself. One thing that I've done is repeat a couple of the weeks if I've felt that I'm not up to moving on. I did week 2 twice, and I did week 5 for ... um, nearly 4 weeks I think. I'm on week 7 now. Don't feel like you're tied to the exact number of days of the program.
Add in some weight training or body weight training. When you lose weight, you lose fat AND MUSCLE. You want to avoid losing muscle as much as possible and the way to do that is eat more protein and work the muscles. You don't have to have access to a gym to do so - although I'm sure at school you have one. Things like squats, lunges, pushups, dips, presses, etc., will help. And you can always buy a set of inexpensive weights to help.
I try to be "good" and starve myself all day, only to cave in and eat tons of junk
Starving yourself all day is not "good" in any sense of the word. In fact if there was one truly horribly rotten bad thing you could do while on a diet, going all day without food is probably the #1. Your body needs to be nourished. If you go all day without eating, you're going to create exactly the situation you did: when you do have access to food, you binge and shovel junk like there's no tomorrow. The best thing you can do for yourself is eat as regularly as possible and NOT starve.
I like to stay up late (as you can see by this post) and sleep late. I'm in the habit of rushing out the door to the university without breakfast/lunch. Not good, I know.
There's nothing wrong with keeping odd hours. I'm naturally a night owl and when I used to work from home, I often slept until 11, worked through the afternoon, took a long break in the evening, and then worked again from 10 p.m. until about 2 or 3 a.m. when I went to sleep. Keeping odd hours should have nothing to do with eating healthily. You can still eat something when you wake up, eat something a few hours later, and so forth. So what if you're having "breakfast" at noon and dinner at 10:30 p.m.?
You must get in the habit of eating something in the morning. If you are one of those people who rushes around like crazy in the morning, then prepare something the night before. Or fix something fast and portable that you can take out the door with you. A serving of peanut butter spread on a whole grain english muffin, a boiled egg sliced over a piece of whole grain toast, heck even a turkey sandwich ... you need that morning meal.
As far as your "willing to do" and "not willing to do list" ... I think it's good that you know what your limits are. Too many people go into dieting thinking "I'm going to change my whole life" and then when they can't, they give up. AT least you are being honest with yourself right up front and I think that gives you a better and more realistic view of what you can accomplish.
That said, check out my post about free days here:

I personally believe in living my life and enjoying it. Yes, it means I don't lose weight as fast as I could, but I'd rather be healthy and happy, than miserable and give up and stay fat.
Hope all of this gives you something to work with and help.
