Karen has great advice. I am assuming you are Type 1... but even if a T2 on insulin, it is very true.
Even in my years of denial (choosing to ignore the fact that I was Type 1) I always took my insulin. You have to..no other choices. You will never be able to control gluccose levels without insulin. Even if you choose to ignore all the fine points, eat whatever you want no matter how it harms you, take the insulin and check your blood glucose level.
Are your keto strips expired? If they are negative, if you do not believe them, check with a doctor. DKA can be very harmful.
