Doctor pushing insulin on me

I feel crazy and don’t know where else to go for advice. I failed the 1 hour glucose test miserably but they told me I didn’t need to fast before it so I ate something a teensy bit sugary. My fault there. Instead of doing the three hour test I opted to test my sugars for 2 weeks. Well 2 weeks later and I didn’t have a single high blood sugar reading. And that’s without changing my diet. I could eat whatever I wanted and have a normal if not low blood sugar reading. They’ve since said I need to keep testing my sugars 4 times a day and even consider insulin to get my numbers in “control”. I’m at a loss. I don’t know what more insulin could do if I’m already in target range for numbers. My fasting numbers were all low and I even had low numbers after eating. I’m talking one night after dinner I had a 75 reading when it was supposed to be >140.

This is close to my last straw with the care i’ve received. I feel like they’re not listening and are pushing problems on me that I don’t even have.
