Don't be embarassed about what you ate yesterday, concentrate on today as it is a new day and an opportunity for you to do things in the way that you want.
It might help by setting yourself goals one day at a time rather than looking at the future as a whole. If things slip one day, you can then look to the next day as a fresh start and recognise that it was a bad day yesterday but that you are going to have a good day today. Don't be hard on yourself.
I am really sorry that you are having such a hard time. At the risk of sounding terribly patronising (for which I sincerely apologise!) it sounds like there is definitely elements of your life where you are in control, even though you don't think that you are. You recognise that this illness is something that you want to overcome, you are talking to others about it and you recognise that the eating vomiting cycle is destructive and not a means to control your problems. That really is half the battle.
You say that you seem to go from one problem to another - what is upsetting you at the moment? Don't be tempted to trivialise your problems by saying that you should cope - the fact is that you are finding things difficult and that is ok. Maybe by talking about the things in life that are causing you a problems, you will help to resolve or at least alleviate the problems with your eating, which is just a coping mechanism.
I saw a counsellor for six weeks for anxiety and depression a while back and I didn't do it through my GP - I only told my dh so nobody knew anything about it and I just paid for it at £25 per week. It felt like "me time" when I saw my counsellor but at the same time, I was anonymous so it didn't matter.
I was amazed how many life coping strategies I developed from it and how when I feel bad now I can go back and remind myself of the things I learned. I still have days where I feel bad but I am more forgiving of myself and this might really help you and to help recognise the areas in your life where actually you are really doing a great job.
I am not pushing you into going to get professional help unless you want to do so or until you are ready. All I am suggesting is that getting things off your chest to an independent sympathetic listener might really help and you wouldn't even have to talk about your eating problem unless you wanted to.
I really do wish you good luck with this. I have seen how much this upsets my friend and I know that it is not something which is easy to overcome but people do manage and you can do it. Draw as much love and support as you can from those around you and don't judge yourself so harshly.
I will come back to this posting when I can. I hope that you have a good day today.
