I am 13 almost 14 and I would like to lose almost 100 pounds but I'd like to lose at least 60 pounds in month?

It's kind of impossible to answer this question correctly because you didn't say how much you weigh. I'ts pretty much impossible to lose that much in a month. just exercise alot and eat smaller servings and healthier and the lbs will begin to drop. but it will take some time.
