Im on a diet but for my birthday I received a TON of candy?

I just turned 15, and for my birthday I got this (among other things of course) : A bag of chocolate covered pretzels, a bag of Sour patch kids, and two 11 ounce bags of Skittles and Peanut M&Ms. I love all these things, but Im trying to lose weight. How can I work these into a good plan? I still want to eat them.
