I need help so bad.. Food addiction

Hi everybody:
I have a huge problem and I need help so bad.
I can´t stop eat. sometimes I try to eat healthy but that last 2 days as much. after that Im desperate to eat carbs, and I end up eating all the carbs I dont have during that two days eating healthy. Carbs make me feel like drunk,"happy", my reality is totally different when I eat carbs. I know is an addiction. I'm totally down. I have gain weight (30 lbs) and I hate my self for not to be able to stop this nightmare. When I eat at night hardly can sleep because of full stomach, even I have waking me up drowning and is hard to back to breathe because of the reflux. Im desperate. Please help.
