How can i lose a lot of weight as fast as possible?

Im 16 years old and I am extremely over weight. How much do I weight? 260lbs!
I know im a , and thats the problem im too fat I cant get a date I have no friends! And its because of my weight!!
Can you please help me lose the weight by giving me...

ideas/suggestions?
It would be greatly appeaicated!

2 things-
Give up all fast food. I mean it fast food is nasty and unhealthy.
Running. I don't like exercise. I just have no time for it. The idea is to push yourself to the limit. Run every day and when you are about to give up just make a small goal for yourself. For example my school track has all these symbols and lines and numbers on it. So if I was about to give up I'd say to myself 'I'm going to make it to the number 2'. And then when I'm at the number 2 it won't seem like a big deal. Then I'd go a little farther and so on, until I can't push myself anymore.
You have to have the ambition, the want, the need, the dream.
Dream to be healthy.
And also I know this girl who is really over weight who's also really popular. She wears string shirts and mini skirts and she doesn't care how she looks. It's your attitude.
I want you to try something. Stare at yourself in the mirror and cry. Cry at yourself. It's a pretty weird feeling, trust me. Then laugh. Point to the fat and say 'I control the fat; the fat does not control me!' :D Good luck!

No it isn't... its because you have low self-esteem, and its affecting your personality.
