I've skimmed over a lot of text and picked up some interesting things in here.
1. Most of you here, who have an eating disorder, is because OTHER people made you think you're overweight.
2. You start to not eat at all and exercise at the same time.
3. Irregular eating patterns.
All of it is the WORST thing you can do to your body, hence why it is an disorder.
First of all: Seek help from a professional, whether that be a psychologist or a nutritionist, doesn't matter, get help. Or try to find a support group, who can help you as well.
I used to have a very irregular eating pattern. Didn't eat until lunch, only ate grilled cheese sandwiches for lunch and then just dinner. No snacks, no extra's just that.
But I did exercise a lot beside that and would result in me feeling ill, dizzy, on the verge of fainting.
This weird eating pattern was caused by a sudden depression that hit me after getting out of an abusive relationship. I lost 22 pounds in 2 weeks, which toppled me into being underweight and that was alarming, since I was already considered to be a bit on the skinny side with my normal weight.
Now, I start my day with coffee at 6:30, eat at 10am, (2 croissants with cheese and some juice), eat lunch at a 11:45, which is usually a sandwich with all sorts of toppings. (My favourite is lettuce, brie cheese, tomato, cucumber, honey and roasted pine nuts.) Along with a soda and a candy bar for sugars. I have another snack at 14:15, which depends, it's usually a slice or two of gingerbread for fibres and sugars. Then I can have a fruity/vegetable snack at 16:00 and I usually have dinner at 19:00 or 20:00. Which is your average vegetables, potatoes and some meat. And after dinner I can have some snacks like crisps, cookies or something, but I usually just resort to tea with a biscuit and that's my day.
I work of course (quite heavy physical labour), hence why I eat at such odd hours. And I exercise after work. (Nothing too excessive, just taking care of my pets, taking them out for walks and things, some weight lifting because of them etc. which is considered to be exercise.)
It took me about a year to get those 22 pounds back. (I should've gone to a nutritionist back then, but I didn't think of that. YAY depression!)
My weight has been consistent for about 2 or 3 years now. I eat junkfood whenever I feel like it. (Which is about once or twice a week.) I don't calorie count, because I'm too lazy to figure that s**t out. I eat whatever I feel like, drink alcohol on some weekends, eat quite some sugar on weekends too.
I don't gain extra weight, because I stop eating when I'm full. My exercise helps me too and I just listen to my body.
If I'm hungry, I eat more, if I'm not that hungry, I eat less.
And my hunger is based on what I do during the day. Regular workday means regular food intake. If I don't work and laze about all day: I'll eat significantly less. If I am on holiday (which means I'm either at the beach and awful lot or the woods, just hiking, horsebackriding, cycling etc) I'll eat more, because I burn more calories than usual.
Anywho, this is my two cents on it and how you can help yourself. Eating disorders are usually caused by something. Whether that is peer pressure from society or some other ailment.
You can over come it, get the help you need. Maintain a healthy balanced* diet and try to exercise what is comfortable with you.
*Healthy doesn't mean you can only eat vegetables and superfoods. Healthy means that you're allowed to have a snack attack, but balance it out with more fibres, more vitamins and exercise afterwards.
