I'm sorry I didn't mean to cause any offence being flippant with my earlier post, and I'm sorry to hear you have eye problems so early on, that sucks.
I think the issue is that a lot of us would love to have the control that you have, you're doing amazingly, probably helped by a slightly functioning pancreas. Whereas you would love to have the variety and attitude to food that many of the rest of us have. So there must be some middle ground somewhere! But OCD and anxiety about food will make things difficult, so please do try to get/find some help with that.
I would say I don't eat that differently to before diagnosis, really. I don't have sweets or fizzy drinks any more, but anything else pretty much goes, in moderation. Certainly I take the approach that if I don't try something then I'll never know, and so I'm willing to try most things or new ideas. If it goes wrong I know I can deal with it, so try not to worry. Most people I meet don't know I'm diabetic because I don't ask for special foods or anything, and do a lot of exercise and don't like to make a fuss, so they're always surprised if they find out.
Believe me, I did have some very bleak days early on in my diagnosis, and I was thinking I was quite limited on food at first (I was on mixed insulins too, which didn't help). I was at an age where I was constantly attending weddings and christenings at the time, and what I could eat and when were a big stress. But after going on a DAFNE-type course and switching to MDI I decided I still had to live and eating and enjoying food with family/friends was a big part of my quality of life (I'd always been told off for being underweight too!) so I try to just eat healthily without going to extremes. I have a BMI of 19 now, nice and healthy. I remember getting a reading of 8 before meals and crying because I felt like every high reading took me closer to my feet dropping off! But actually you can't carry on like that, agonising over single readings. You just have to correct, try to learn from it and move on. And a single high reading is not going to do any harm in the long or short term, it's just annoying.
Low carb was relatively new to me after joining this forum. I can see the benefits but equally I find it confusing too, e.g. if I have just eggs for breakfast I need to bolus, but with trial and error I can get it right. Sometimes it's just simpler to stick to more normal meals. I try to go relatively low carb/low GI for breakfast (today was a hot cross bun, but cycled to work afterwards!), then lunch is a sandwich with fruit and a yoghurt, yes a carb fest but it's easy and I try to inject 30 mins before eating to avoid a massive spike- this came with trial and error. Tea today was stir fry with noodles- I find a don't get a big spike with tea as it seems to digest quite slowly, so noodles, pasta, rice, potatoes are all fine. I often split my tea dose over a few hours to avoid a hypo.
Hope you get some help, and try not to obsess over the small blips, easier said than done I know!
