I apologize in advance for such a long post. I am posting this in the forum instead of sending a private message on the off chance that someone with your same issue might be reading this.
I suffered from bulimia for seven years. It took a year of therapy before I could control it. I stress that I am NOT a therapist. You NEED to find one. Keep asking for different ones. Or, better yet, ask for one that deals SPECIFICALLY with ED's. My therapist once suffered from bulimia herself, so she easily identified with me, and could almost finish my sentences.... they are out there.
Almost every person with an eating disorder is clinically depressed. There are drugs to help you. You don't need to take them for the rest of your life, but let them help you through this difficult time, until you are back in control.
Next, I want to stress that you are placing yourself in REAL DANGER. I have witnessed first hand someone dying from binging and purging. Her heart stopped. You can read her story here:

I understand the feelings that come with binging and purging. I could enjoy a fest! I could eat anything and everything I wanted! ...And then get rid of it. It felt like I was correcting a mistake I had made. I had the power to control what my body ingested without the world knowing. I once tried confessing my shameful secret to some college "friends", who passed it off as a lame cry for attention. I decided then that no one seemed to care and it became my little secret. I was so good, I kept it a secret for years... Whenever complications came up, I convinced myself and others that I had some mysterious illness. I only confessed to my boyfriend (now husband) after it really felt like the weight of the world was on my shoulders. I knew I needed help.
You need to figure out what it is that triggers a binge or a purge, and by all means... AVOID IT! Recognize your own body's signals to stop eating. Even enlist the help of your husband if need be. My husband would sit with me for 30 minutes after each meal, until the feeling of "fullness" and the urge to purge had passed.
You need to figure out where your drive for food is coming from. Is it emotional? Probably. And you have already pinpointed it back to when you were picked on. When you were in middle school, food was your comfort. It made you feel good and it was always, always there for you. But that's all in the past. What is happening in your life RIGHT NOW that makes you so unhappy that you still feel the need to turn to food? Is it a personal relationship? Is it a workplace issue? Your Eating Disorder can not be the answer to this question. Your need to binge is a secondary emotion. You need to find the first emotion.
Next, you need to figure out WHY you are so hard on yourself. Did someone tell you that you need to look a certain way? Act a certain way? Do you constantly walk around thinking everyone is looking at and judging you? Even staring at you? You are SO SURE that your husband/mother/friend/ would love you more if you lost weight/were less difficult/better at something. Well... did they tell you that? People with ED's fancy themselves mind readers. "My boyfriend thinks I'm fat" "My friend is trying to drag me down with her!" etc. .... I'm willing to bet all the gold in the world that you CAN NOT read minds! The truth is, it's all in yours.
That brings me back to stressing the importance of getting professional help. Eating disorders do not just "go away" because you will it. It takes time and the right therapy. DO NOT GIVE UP. Your life is at stake.
