Hi and welcome to the forum.
So sorry to hear that you have struggled with your diabetes and an eating disorder and you are now suffering complications.
I too have difficulties with my relationship to food and I am very much an all or nothing person. I was a sugar addict and comfort eater pre-diagnosis but I used all the negative feelings I had at diagnosis (guilt and embarrassment etc) to motivate me to change..... I too was initially assumed to be Type 2 and in some respects that helped me because I went all out to try to reverse it by going very low carb. By the time they figured out that I was actually Type 1, I had found that my comfort eating and cravings were greatly reduced by following a low carb way of eating. I also benefitted in other respects in that my 20+yr acute migraine problem stopped when I changed my diet, my joints were much less painful and I lost weight. I started to feel stronger and fitter and healthier than I had in a lot of years and without the cravings I was in much better control of my eating.... and I like control. When I started insulin, I was told to eat normally, but I had no real idea what normal was because I had gone from one extreme to the other ie. very high carb to very low carb and I didn't really trust myself to go back to eating a normal amount of carbs because I knew it was a slippery slope for me. I had a couple of weeks were I increased my carb intake a bit but I felt like it was dangerous ground so I stuck with low carb. That was 4 years ago (I was diagnosed late in life) and I now feel that I can remain low carb for the rest of my life, give or take the odd social occasion where I am left with little choice. I have significantly increased my fat intake as this makes the food I eat satisfying and enjoyable and slows down my digestion so that I don't get peaks and troughs and I find this works pretty well for me. I am not saying that I don't fall off the wagon occasionally but it is only for a day or two at the most before I actually long for a refreshing salad and my control back. I really enjoy my food, maybe more now than I did before because it is almost like I eat in colour now (not just looks wise, but taste wise too). I savour my special treats and I make sure I have a treat every day, sometimes more than one. My main treat of the day is a coffee with real double cream in the morning and I really like to be "in the moment" with that coffee. I know it sounds cliched but I think part of the change in my mentality is eating my food more slowly and seeking out the individual flavours within it and texture is really important too. I really like crunchy foods much more now than I did before.
Anyway, I appreciate that my disordered eating problem was much less severe than yours, but this is what has really helped me. I don't eat bread or pasta or rice or potatoes or cakes or biscuits or sweets (other than jelly babies for hypos).
My breakfast is usually creamy Greek natural yoghurt (not low fat as I need the fat in the yoghurt to stabilize my BG and energy levels) with a few berries (currently stewed rhubarb from the garden though) and mixed seeds and sometimes chopped nuts and cinnamon and/or ginger....plus my coffee with cream.
Lunch is usually a half an apple with a chunk of really nice cheese (currently smoked cheddar) or a bowl of soup or a salad with boiled eggs or meat or sometimes tuna and mayonnaise wraps made with lettuce instead of bread or veggie sticks with sour cream and chive dip (the real stuff from the chilled counter not the Doritos stuff in a jar.... processed foods are part of the disordered eating problem i think, so I try to stick to real foods as much as possible)
Evening meal might be a veggie curry or stir fry or chilli either with Konjec rice or noodles or just on a bed of more veg. Or I love ratatouille which I batch cook and have that with meat or grilled cheese or traditional meals like high meat content sausages with mash but use mashed cauli instead of potato with a good dollop of cream cheese mixed in and plenty of other veg, mostly green leafy veg which is usually cooked with a knob of butter. Gammon with cauliflower cheese and broccoli, but the cauli cheese is just made with cream cheese and grated cheese instead of a cheese sauce with milk and flour....
Anyway, that is just an idea of what I do and how I go about managing my disordered eating. Some days I just need one or 2 meals a day and if I can get out for a good walk that definitely helps with wanting less food as does keeping busy.
I am not sure if any of that is helpful to you but it really has changed things for me in lots of positive ways. It wasn't easy getting started as bread and potatoes were a cultural staple of my meals and bread in particular is a carrier for so many other foods that it posed considerable difficulty at first as it is just so convenient, but gradually I got used to not having it and now I really don't miss it and the odd occasion where I have some at social events I am left wondering what I thought was so great about it. Admittedly mostly these are not occasions where the bread is top quality, but I see this stuff as mostly bland, beige stodge and I like food with lots of flavour now.
I believe there is an organization called BEAT which helps people with eating disorders. I think
@Inka may know more about that. I really hope you are able to find a way forward with your eating disorder and find a way to manage your diabetes better. The modern technology we have today with CGM and pumps and stuff can take a lot of the burden out of diabetes, so that might be something to explore with your diabetes team at the clinic if you are not already pumping, but obviously your eating disorder needs addressing and we are here to help you in any way we can here.
