I'm 40. I have been battleing my weight for 20 years. I have always been either losing or gaining. Down 40 up 20, down 10 up 30... Today I am 40 pounds overweight again. I don't eat regular food anymore. I don't want 3 meals a day. I only want to eat anything bad for me. It is like I am purposely killing myself. I will eat an entire box of doughnuts instead of meals for a day. I will eat french fries all day long instead of meals... I cannot seem to shake this habit. When I start on a new diet I am successful to a point-- I re-train myself and force down real food. I can only do it for a short time though before the above pattern returns.
I also feel like I am not normal in general. I have started to notice that I have trouble conversing and there seem to be more blank stares at me than ever before. I actually feel like I am going crazy. I can't think clearly any more at all. I am completely unable to focus on anything. I shy away from social situations. I am generally unhappy all the time now. I have diagnosed myslef with depression, anxiety, ADD, but have yet to go to a Dr. I am worried they will throw a bottle of pills at me and that it will open up another can of worms. I want to go to someone who will look at my entire person and I want to be a different person. What kind of Dr. will do that?

You have two issues one can have effect on the other.

One is just will power to eat regular meals, and if you do't buy boxes of doughnuts you don't eat them.

And your diagnoses is well just that a guess at best. I would start with my regular family doctor and go from there.
