Winter, honey, if you feel as though it's becoming detrimental to your life then it is in fact, a real problem. If you find you change your mind to your normal plans to accommodate your disordered thinking towards food and/or body image, then it's an eating disorder at the most elemental level.
The fact you felt the need to tell us about it means it's really hindering you and plaguing your mind. If you didn't really believe it was a problem, you wouldn't have mentioned it! But the fact is, you've told us now. You know it's a problem and you're nipping it in the bud.
Unfortunately the most frustrating element of all eating disorders is the point in which you know where the problem is, how it came about, and the elements harming you, but you are unable to break out of the monotony. This is a long and arduous task to recondition your mind to realise you're incorrect, your thoughts are broken, and up is not down after all. But that is why I set up the thread, and that's why I exist; as a mere conduit and pseudo-helpful life pop-up to help with all my friends here. It's a long process, but we're always a click away.
Rubix, one thing I'm super-proud of you about - you're very, very intense about the prospect of getting better. A lot of people consign themselves to the thought that it's beating them, so why bother?
Sometimes an eating disorder feels like a whirlpool. You wake up on the edge of the torrent, and swim frantically to escape the pull. Some days, you exhaust yourself fighting that current. Some days, you swim so hard, but one slip and you're pulled straight in. Some days you give up swimming and just "go with it", and when that happens, you get pulled right down to your worst point. The point I'm making is that the feeling of struggle is POSITIVE. It means you're making progress. As you make further progress, the struggle is still constant, but less exhausting. And this is a strange thing because you assume "cured" means "totally better", but in reality it's just the lessening of exhaustion; you just become less and less helpless.
What I mean is, you expect to be getting stronger; but in reality we are all just becoming less weak.
