Do I have an eating disorder? What can I do about this? How can I convince them that I don't?

From what you say, sounds like you certainly have some sort of eating problem and a dad who is worried sick about you. Reread what you've written, specifically:

I keep a food diary and if I go a whole day with no calories then I feel like I am starting to get somewhere in my life, that somewhere being me getting thinner. I just want to be the "ideal" weight and I don't know what that is, but I know that one day I will get there and then I will know.

Please get yourself some professional help.

Very best of luck.

It does sound like you have an eating disorder of some kind, which would be best to seek advice about as they can bring a few problems your way. Your Dad sounds genuinely concerned and from personal experience I know some Dads find it hard to have Daughters.. it's a whole new ball game and they don't know where to start.

I think most teenage girls want to loose weight, though I noticed you never said how much you actually weigh or your height. If you do want to loose weight it's best to speak to your Doctor and see what they have to say. They will usually advise you on what is best - which is more often than not a healthy diet and exercise.

If you don't eat, you risk your body storing the calories and fats from your next meal. It will prepare itself for the next fast. Therefore, it is best to eat breakfast and 2-4 balanced meals throughout the day, including fruit and veg.

At risk of sounding like a text book I'll stop there, but I'm sure you understand. Is there a friend or family member you can talk to instead of your Dad? Sometimes a problem shared really is a problem halved.

I hope things work out for you, I wish you the best of luck with your anxiety and depression, and your food issues too. CAMHS are there to help. Take care.

I'm pretty sure this is an eating disorder, but I'm not sure if it could be called anorexia... Maybe, but I'm honestly not sure because I'm not really someone to ask about eating disorders. My aunt (who is the same age as me, so she's a teen...) had anorexia, and she is still, even after therapy, constantly checking calories and making sure she's an extra small at Aeropostal. It's terrible to see what she does to herself. She hardly eats and when she does, it's fruit or like two crackers and a water. She's always obsessing over it. What you've told us reminds me of her, always checking calories and trying to not eat. Maybe you do have anorexia, but I think that since you do see someone for depression you need to tell them. I feel like a hypocrite telling people to tell adults, when I can't even tell my parents about my problem, but honestly, if you really want help (which you do, because you're asking a question on here) I would tell an adult or a friend at least. :)

I'm sorry, I think you do have an eating disorder. Please get some help.And if you are worried about how you look, ask your doctor if you are maintaining a healthy weight for your height and age.

Please tell your therapist/CAMHS about this problem.

Assuming you're not trolling, from what you say you are clearly anorexic. If you carry on like this you will die.
