@Toto; You are doing so fudgingly awesome Monsieur Le Toto! Magnifique! Don't worry about weight gin being too fast or too slow or what have you. It happens. To get to where I am now I gained in unregulated spurts (won't mention numbers, hell I'm dealing better with things by not KNOWING numbers.) Shifting clothes sizes is good too, it means an excuse to reinvent how you dress an' all that!
@Riku; sounds like you are in the level 1 service.
Level 1 - General GP work
Level 2 - Counselling
Level 3 - Specialised Support
Level 4 - Hospitalisation
Level 5 - Fed through a tube
You can ask to be upped to a level 2 service, don't ask for level 3. Generally if they are iffy at the moment being upped level by level is a more considered approach. Tell them what you want. Spoke to the leader on the team in my area and apparently GP's are fairly useless in dealing with ED's, she said when moving to a new area just tell them straight up what you want as they won't really understand otherwise.
And don't take recovery as a lent thing! It gives the impression you can do it afterwards or something! Just, breathe. I used to have the, ummmm, vomiting bug too, the entire disengaged feeling, the feeling that something needs to be done in that state. Eat? Generally high on the needs list of people, right? You drift towards something. Food, drink, drugs, your vice.
I've found a couple of things helped like mindfulness meditation. Do this when not in a 'hypno state'. Just close your eyes and concentrate on what is going on inside of you. Watch the images in your mind as they float by. Feeling the air filling your lungs. Don't think about the future, concentrate on experiencing the here and now. I've found it's able to drift into the other areas of life. I've also found doing something that gets out what you are thinking about out of your head helps too before it builds too much. Painting? Writing? Singing?
Your choice.
Personal thing, a little contradictory to what I said but something that reinforces it also;
