Adding to the good advice above, it sounds like you have identified that your eating is emotional. I would really hammer home journaling on that...time, food, mood, circumstances before you eat, and how you feel after. The first step would be to chart everything; the next step is to make substitutions for eating.
Eating is a coping skill for a lot of people. It's not a great one, but it's better than some (say, illegal drugs). Once you know your triggers, you are ahead of the game.
You also mentioned control, which is another biggie; eating (or refusing to eat) is also a control issue for some. You might take a look at whether or not you are feeling out of control over some other areas in your life and see if making some adjustments there could reduce the urge to do so with food.
Finally, closet eating sounds secretive. Do you have a history of getting negative messages about food or your eating? If that's there, it's also something to explore.
I realize that this is more than the answer to your question about having a food buddy; sorry! Just getting some thoughts out there, which as with any advice here you are free to take or leave. If history is any predictor, there will be several folks who would volunteer to buddy up with you.
Good luck, and good job recognizing that you want to get a handle on this now
