@kaylz91 , sorry to hear you're having problems.
If I recall rightly from earlier posts, you've been dx'd recently.
One of the things which sometimes happens in newly dx'd is that they're fairly upbeat about it to begin with, they spend a lot of time figuring out carbs, ratios etc. etc., feel hopeful that, yeah, this ain't too bad, just need to do a bit of carb counting, I can manage that, then they get a run of unexpected, "sorry, what the f just happened there?" results, and it doesn't seem that easy anymore. There's frustration that they've followed the rules but it still hasn't worked out. Believe me, I've been there.
You've not said what the nature of the food problems is, and I'm not going to ask, but I wonder whether you've maybe reached that stage where you've been doing everything right re carb counting and are getting frustrated that it's not working out as much as you like.
There's no easy answer to that, other than accepting that honeymoon can throw a few blinders, and even once that's gone, there is always an inherent randomness in T1 which means it'll never really go to plan all the time.
It's a bit like starting a new sport or job. To start with, you're learning the basics so there'll always be a few flyers, but over time you'll pick up more and more experience which'll let you do those Andy Murray net shots that you would never have thought about a few months in (and AM still screws it up from time to time - see recent Wimbledon results!).
I don't know what factors you're taking into account when you bolus. Carb count and bolus for that particular meal are the obvious ones and I'm sure you're doing that, but I think sometimes newbies just look at those two things without realising that they don't exist in isolation.
I always try to bear in mind that every bolus isn't fire and forget - it'll be kicking around for 4 to 5 hours, and that will have a bearing on how I dose if I'm eating again within that 5 hours, as will how much I've exercised in the 6 hours before a bolus, anticipated exercise after the bolus, what the GI of the food is, how I've generally been running for the last few days, what level I'm at when bolusing, how far in advance to pre-bolus.
That's a lot of variables to think about, and you're not going to learn it all so shortly after dx. But you will as time goes by. I hesitate to call it intuition, because that sounds too much like guesswork, but you'll reach a stage where you've dialled up x units, got the needle in you, and then instinct from experience just tells you, nah, I reckon another 1 or 2 plus or less would be better and you'll dial it up or down as accords - they don't teach that in hospital, fiddling with a dose while the needle is in!
I've got my head round it by accepting that it is random (the liver does odd things like releasing or taking back glucose without asking me about it), so I don't expect it to play by the rules.
Instead, I think, ok, I've carb counted for this meal, most of the time, it'll be fine, but, despite best efforts, I know that it won't work all the time, so I'm fine with a 10g tweak up or 2u nudge down a few hours later if need be. Co-operate with the randomness - it's not a failure, it's part of the treatment.
That approach is actively encouraged by docs who understand cgm. If you can afford cgm, get it. It makes life much easier, being able to see levels moving and pro-actively taking steps to stay in range instead of reacting after the event once they're already out of range.
Best of luck!
