Insulin Resistance

Hey all,

So I have posted a couple times on here now. I have been going through a rough patch with my BG for the last couple of months. I just cant get them to a controlled level.

Backstory: I was diagnosed 4 years ago at 24 years old. I was on 12 units of basal and 1:10 carb ratio. Activity level - on and off exercise. I am 5'9'' and weighed 115lbs at the time of diagnosis (very underweight for me).

Currently: 28 years old. Basal has increased from 14 units to 20 units in 3 months. Carb ratio is either 1:6, 1:7, 1:8. (compared to 1:10 a couple months ago). I have been constantly fiddling with all of these units for the last 2 months. Activity level - inactive for a year now (maybe occasional walks and house cleaning daily is the extent of it). I now weigh 140lbs. This is pretty standard and what I weighed post-diagnosis. My father passed away a month ago. In August 2018, I moved from Canada to the US, got married, and started a new job. So all this sounds stressful, yes--- but I do not feel stressed at all. As a result, I feel like that cannot be affecting my BG.

I think I had a decently long honeymoon phase and I am now coming out of it. I try my best to be carb conscious and pick lower carb options when I can. Since my BG is starting to spike sooo often (usually 14-17 after meals) when I am eating the same meals daily and giving myself the same amount of insulin, I am starting to fear that I am becoming insulin resistant. Is it possible for that occur so quickly?? I have only had Type for 4ish years. I am not overweight. I don't exercise- yes. But I would classify my diet as healthy.

Anyone have any advice or thoughts?? How can avoid insulin resistance and/or increase my carb ratio. It's depressing to constantly be increasing my units daily-- I feel like I am failing myself and my body
