What can i do to get in shape in 15 days?

im going on vacation in 15 days. ive been eating pretty badly because its summer and its starting to show. im not definetly fat, but im definetly not as skinny as i was at the beginning of the summer. i have a little extra fat on my stomach and thighs. im 15 years old, about 5'1-5'2, and im not sure how much i weigh because my scales broken, but im guessing around 105-107 lbs. im running 2 miles everyday, but i usually take a 5 minute break in between the miles. is this going to help me at all? and also, what else can i do to get in shape?
