Sorry ... really long post ahead here!
I free feed because I worked outside the home for 12 years of our cats life so now they are just used to having food there all the time.
I understand, Olivia, I really do! My cat used to be a dry-food addict, too. Bat-Bat was free-feeding for almost 10 years, mainly because (if I'm totally honest with myself about it

) it was just a heck of a lot more convenient
for me, given my very busy schedule over those years ...
I am now firmly convinced that free-feeding her almost 100% dry kibble was a big factor in her developing diabetes, and Bat-Bat had ballooned up to 18 lbs.

(Her optimum weight is 11 lbs; she's pretty big-boned & long, for a female cat.)
So then I started trying to slow my chow-hound, dry-food-addicted kitty down on the eating, & cut back on her dry rations some: Used a "kibble ball" (she had to play with it/get exercise in order to retrieve the dry kibble bits inside), and even a bought a special bowl that looked like a flying saucer (she had to dig the dry kibble out of various holes in her "spaceship" in order to eat it).
When she'd lost a lot of weight over time, at first I was relieved ... until I found out that the
reason she'd lost all that weight (oops, down to about 9.5 lbs!) was because she was - by then - severely diabetic.
I have attached two documents here: Both are by veterinarian Dr. Lisa Pierson, who is known as one of the foremost experts on healthy eating habits for cats in general - and on the whys/hows of feeding of diabetic cats in particular! One is a food chart for your reference - there are so many,
many choices in low-carb canned foods.
(I feel confident that you'll eventually find some on that list that Bubba ends up loving!)
The other doc provides great tips for transitioning dry-food addicts to wet/canned foods - I strongly encourage you to read this. (And yep - it usually
does take some time!

)
Olivia, I know that having a diabetic kitty in the household is stressful

and overwhelming

. Believe me,
everyone here knows the kinds of feelings you've been having since being told that your kitty has diabetes. (There were days, in the beginning, when I just wanted to crawl into my bed and cry!)
Some of the changes/challenges we face in learning to treat our sugar-kitties effectively can feel really daunting at first, but it's all "do-able" - just ask anybody here! Please know for sure that all of us @ FDMB "have your back" ... we're here to support you; to cheer you on and to help ensure your success in treating Bubba.
Let me know how Bubba's eating for you today (as we definitely want him to eat) and
please avoid that two-hour window before his p.m. pre-shot time, as we
want him to be hungry so that he'll eat right before he gets another shot of insulin. Tonight, if he's around the 160's when you test at shot-time, WITHHOLD FOOD, wait another 15-20 minutes and test his BG again to see if it will rise on its own while he's anticipating his dinner. This may take 2-3 rounds of withholding food & retesting before his BG rises. (It has taken me up to an hour of that routine sometimes to get my girl's BG to rise all on its own.)
As to why he had to skip a dose again this morning: It may be that his body is still recovering from too high a dose yesterday morning & the resulting deep BG drop mid-cycle; it could even be that his pancreas is actually starting to kick in. (Wouldn't that be great!

)
Time and careful monitoring over the next few days will start providing you some clearer direction. (Am I correct in assuming that your vet didn't give you much in the way of instructions when he started Bubba on insulin, except to tell you to bring him in for those BG curves in-office?)
