Overeating At It's Finest

For the last three weeks I have been under tremendous stress, my emotions are out of control like a blazing wild fire, and I have been eating constantly. In the past I have noticed that I turn to food when I am under any kind of pressure. It is my comfort. But the last couple of weeks I have literally been eating until I am sick. I have gained 15 pounds and I don't know what to do. If I continue to eat like this I fear that I will become obese. I am already slightly overweight and I certainly do not need to gain any more. I tried to consult my parents about this problem but they wouldn't take me seriously so without a doubt I again turned to food and binge ate. I don't know what to do. How to I get help? What do I do? Something needs to change!
