Bad Relationship with Food.

I remember when I was fatter; when I would eat whatever I wanted and not even think twice about it. That was bad, I understand but when I first began to lose weight I did so even though I still paid no attention to what I ate. This time though it is harder. I have developed an awful relationship with food where I grudge every bit of it that enters my mouth and meticulously count the calories - even if I don't enter them on MFP. I went through a period of about 4 months where I binged and purged but I got over that by myself; I'm not going to say that I don't still feel that compulsion to overeat and then purge but I am handling that aspect. I don't think I am explaining this very well.
Since I started this journey almost a year ago I have been living on a strict no more than 1,200 calorie diet but recently I have started to get really dizzy and get constant migraines. I went to the doctor who took blood samples and my blood pressure etc and eventually came to the conclusion that I wasn't eating enough. My heart almost stopped; the thought of eating more made me feel sick and I struggle with a constant fear that I can really feel each mouthful settle itself as fat onto my already flabby and disgusting body. I need to fix this; I need to get a grip on myself, stop thinking constantly about food, calories and start to enjoy my life but I can't do it alone. I wonder if there is anyone else out there who feels like me? Who feels controlled by food and not the other way around?

Basically, I am wondering if there are any people out there who are willing to help and receive some help in return? I hope so because I don't know how much longer I can do this.
