I want to be in control again

Hi, this is the first forum I have joined for binge eating and I'm feeling rubbish about it all to be honest. I'm 38 and I have been binge eating for 30 years. I have just had one of my biggest binges yet (sat in the car outside Tesco) and I just want some control back, so if anyone has any advice or positive change experience, I would really like to hear from you. Thanks guys.
