I can't be sure, as I've never spoken to a professional about it, but I'm quite convinced I have an eating disorder.
I am obsessed with what I eat. Regimented about calories, I often make myself something to eat, when nobody else is around, and 'eat' it standing next to the bin. I chew every mouthful, savouring the taste, but instead of swallowing it, I spit each one out.
I drink pints of water every day, but get through about 3 bottles of Water Balance tablets a week.
I go to the gym constantly, and do nothing but cardio, and no weights.
I have a pair of trousers in my wardrobe, that I've had for about 4 years. They have ABSOLUTELY no stretch in them, and I use them as my 'barometer' trousers. I try them on about 3x a week. Occasionally they are a bit tight. If they are, I won't eat for a few days until they feel loose.
DH has only a vague idea that I diet a bit, but thinks I'm naturally thin.
I'm not. And I hate it.
