Serious help, i think ive made a mistake, or given in again!?

i gave in to my demons again , and only had one big bag of pick and mix which i had for 2 films at the start and end of the day, yep it was big, and filled with lots of fizzys and jelly sweets. I had with each film, 1 medium sized (cineworld cinemas) diet/ coke zero. During the day, i did lots of walking, and i've now calculated using gmaps online pedometer (which actually works it out so it equals less , due to not taking into consideration pace, climate or gradient) how many calories i have burnt. it said around 1200. now do, you guys think thats overtaken what i've consumed?



And on top of this would someone PLEASE WORK OUT my BMR , i am 16 , 6ft , 105 pounds and go on daily walks burning around 500calories a day-(600 some days) and today obviously ive done this.So i COUNT AS ACTIVE



please help, i am paranoid about maintaining the shape of my legs as they are, and don't want to go running, which i used to do daily (2 miles) ANYMORE.Serious help, i think ive made a mistake, or given in again!?
