How do I tell my doc this diet isn't just for me?

I've always been overweight. No matter what I did nothing would help, including dieting and exercising. I finally went to a doctor that listened instead of brushing me off, and he put me on a diet and tested my blood and put me on some meds. It was the first time in my life I started losing weight--great.

But this diet is hard, really hard. I've been absolutely miserable since I started it (3 months ago). I was depressed before but since I started this diet it's been ten times worse. And I don't think the diet is doing me any favors mentally either, as far as dieting and my relationship with food goes. It's made me feel nothing but guilt anymore for any little thing I put into my mouth whether I'm "allowed" to eat it or not. I don't want to go into specifics, but I'm worried that I'll never be able to eat anything again without berating myself over it. I hate the fact that I'll hate myself for eating a bowl of cheerios or even a piece of fruit (sugar/carbs=bad). I know that's not a good thing.

Half the reason why it's been so hard is because my palate is so limited. I'm a very picky eater and I've had the worst time trying to find foods that I like on this diet without success.

All of it has made me so depressed....I don't know how to tell my doctor that it just might not be for me. Because unless I maintain everything as a "lifestyle change" I'll just gain everything back that I lose anyway, and I know I can't do this forever.

I feel like such a failure. How do I tell my doctor that I just can't do it anymore? I tried telling him I was depressed last time I saw him, but he didn't listen well and brushed off my attempts at trying to say that this diet isn't working for me. He told me to eat more protein to feel better, because that's what's supposed to perk me up when I'm so low-carb. Haven't been successful at that either.

What would you do?

I would just go in there and tell him the honest truth. The same thing kind of happened to me, my doctor put me on a diet plan, and I felt like I was seriously dying. I was being starved, and had pains and everything.
I left him and started my own plan.

I use a site called "myfitnesspal.com" to track what I eat and my exercise.
You put your weight, how much you want to lose, and how much you can work out. It will give you a calorie intake, protein, fat, cabs, etc.
I've lost weight on it, and still am, very quickly actually and I'm not that active.
You must stay within the limits it tells you though, or it will not work. I also suggest eating healthier if you don't already do. For breakfast I eat 8 medium strawberry's, 14 baby carrots, and a 90 calorie granola bar, and all of that ads up to 185cal, which is very low compared to other meals, but it's really filling. I thought I was just inform you on this site, since it has worked for many people including myself. And I wish you the best with your weighloss.

I found my doctor not very helpful. I asked for a referral to a register dietitian. I found this to be more helpful.
I am also reading a book on mindful eating.
It is a slow and painful process. I feel, too often, that I failed, but I keep going weekly to see the dietitian. In 2 months, I have lost only 5 lbs. But, as she said, I lost it the healthy way and I am developping better eating habits. If I continue, after a year I will loose 30 lbs, half of what I need too. So I am in it for long term...
Take care

I read a book once that was helpful with "eating". Not exactly about "dieting" butmore about how we, as women, feel about food. Because I think most women do have feelings about food. ( I am not sure I can post a book name on here....can I?)

yes, please do

The book is called "Women, Food, and God" by Geneen Roth. Initially I was turned off by the "God" word ( my issue ), but it had more spiritual stuff. And if food isn't someone's issue they can substitute the word "Food" to whatever the issue is. It really was a helpful book and made me look at my feelings about food in a new way.
