I have been having trouble with food. I was on WW for a while, and then it stopped working.

I have been struggling with my guilt of eating. I am afraid of eating ANYTHING and I weigh myself 2-3 times a day. When I see that the numbers go up, I freak out and become even more depressed. I work out an hour of cardio 4-5x a week. I drink a lot of water. And I'm getting stressed because my wedding is 35 days away. Luckily, I fit into my gown the second time around, even though they had to take it out a bit. (It's a size 10). I'm constantly feeling fat and ugly and depressed. I do see a psychologist, but haven't been to seeing him in a while. When I go out, I focus on how other girls look and constantly compare them to myself. How this one has thinner arms than me, a smaller waist, blah blah blah. I am 5'2" and weigh 137lbs. I have a medium bone structure. When I was in my early 20's I was 110lbs. Could my metabolism have shut down completely? I'm so fed up with lack of progress on losing I don't know what to do. I eat Special K w/ Berries (one bowl) in the am, water, work out, have soup for lunch (the clear broth kind), and then if I'm hungry I'll eat something for dinner. I get sick if I look at food. I haven't vomited in a while. So sorry for rambling, but hopefully you guys can offer some solace. I'm tired of the prison I'm in.
