how to stop binge eating everyday?

I always binge eat every single day now. I'm 16 5'1 and 131 pounds right now. I use to weight 167 which put me in the obese category. I always find myself eating 2000+ calories in one sitting which is ridiculous. I binge on tortilla chips, pastries, pie, and all kinds of junk food. How can I stop? There are tons of junk food in the house and I told my parents not to buy so much but it is the holidays currently and lots of treats are on sale. I gained about 6 pounds already from binging. I tell myself to stop and start fresh the next day but obviously that is not working at all.What can I do? Also, if i eat a very small portion of junk food everyday and keep under my calorie intake, can I still lose weight? I run on the treadmill at least 30 minutes a day. Sometimes up to 1 hour. Thank you for your time and Merry Christmas!
