I don't know which is worse. Pricking my fingers to get my sugar blood level or pocking myself with the needle to inject the insulin.
If I could give you one piece of advice, it would be to avoid elevated glucose at all cost. If you or a loved one has been diagnosed with diabetes, you are probably familiar with what we call hemoglobin A1c. It is a measure of your average recent glucose levels. Do not let it go up. If you have come to the point that insulin is needed to maintain a healthy glucose level, so be it. It is not your fault that you have arrived at this point; you simply need the correct treatment for the actual stage of your Type 2 diabetes.

Please don't despair; there is technology that can help you to adjust the dosage more frequently. Companies have developed technologies that enable insulin dosage to be as dynamic as needed to make it effective for you.
In summary, it is not your fault that you need insulin therapy. It is just another mode of therapy that you need when your pancreas fails. The main challenge is to adjust your dosage frequently. Fortunately, solutions are becoming available to facilitate this.
