Ok, here goes. I've been nice. In fact I've been very nice to you, but your last post sort of lit my blue touch paper. What i am going to write is written by someone who has not always had the greatest relationship with food. My issues were very different to yours, but I write it from the standpoint of someone who has trodden a variation on the path you are on now.
But, @akindrat, I'm frustrated both for you and with you. What on earth were you doing buying those things in the Co-op? You have excellent food in, and didn't need to completely waste your money - never mind what it'll be doing to your system.
Right now, you are f^*+=>g with your future. Your uni course, your progress, your relationship with food, and indeed your health; if not your life. Our bodies can only take so much abuse, but you seem intent of continuing to pile in in the worst way possible. All this yo-yo stuff is incredibly hard on your body. Indeed, possibly even harder than running higher than ideal for a while. In certainly not suggesting you ditch the diet, because you know how I'll you felt, aside from anything else, I'm just giving you my informed, speculative assessment of where you are.
I appreciate seeing your therapist 3 times a week will be taxing on you. Therapy isn't the ma by, lambs easy route anyone who has never had it might imagine. Mit physically and emotionally draining, and may well be a factor in your desire to reach for the naughty stuff. If you are an emotional eater (and I'm certain you are), that's your salve when the going gets tough, but it is also harming you.
You are currently on a journey of self-harming, with your weapon of choice being cornflakes, pasties and other carb-tastic foods. Again, I'm not suggesting there are healthier self-harming options; I am NOT. But you have to see your behaviour in that way? I'm assuming you are discussing this in your sessions (rhetorical statement).
You need to do so,etching today. Your consultant being pleased with your blood scores of a couple of weeks ago means nothing today, if you are eating badly. I'm can't view your image as its too large for the Internet here to deal with, today, so I don't actually know what the numbers are.
Without wanting to sound melodramatic, or a drama queen, you have to get your head around the fact that you are at a pretty big life crossroads at the moment, and only you can take the safe actions required. That's not about saying what you will do, it's about doing what you need to do, and keeping doing it. Min fortunately, this isn't something anyone else can do for you. All the nutritious in the world don't make a healthy diet. For you ditching the carbs and eating a protein and fat based diet do.
I'm sorry if that's all pretty bottom line, but subtle hasn't worked, so far.
Don't get me wrong, I a admire your candour and your open honesty in laming your posts. I hope your therapist is getting this insight too. I admire open, brave people and will offer you ongoing support. But you need to take sustained action or the revolving door marked crisis will always only be a couple of paces away.
Please, please do take some time out to think today. It's your life, but I'd like to see you live it happily, healthily and successfully, not lurching from one drama to the next crisis.
