How Can I lose 60+ pounds in 9 weeks?

Hi I am jenny, I know I'm fat but i am comfortable in my own body, and that does not bother me. I love me for me and so do all my friends and my boyfriend. but I want to get a little skinnier before my next school semester. I am very passionate about losing this weight. For my size it is possible for me to lose all that weight but I am not sure how to do it. I live in Louisiana so it gets really humid... My plan that I came up with is: Get up at 5 get out of house at 6 ( so like eat a lil food and get dressed) then ride my bike down the lab. stretch ( about 12 miles) it will take a total 55 minutes to an hour.. But I am afraid that I am unable to do it. Keep in mind i am a very social person and only 17.. I'm turning 18 in July... I also love Xbox... but i know that should only be played when the sun goes down. I also started to keep track on the Cal. intake. Breads rices and pasta should be lowered if not exterminated from my diet but I am not sure what I should do from there. Please help.
