Failed 1-hour GTT

I failed my 1-hour glucose test at 28 weeks. They had me take it at 12 weeks initially and I passed with a 92. I took it this time and got a 179. Doctor said it needed to be below 140. I’m freaking out just a little bit. I got referred for diabetic counseling and will be monitoring my sugar levels for the next few weeks. I’m stressed out and anxious. Has anyone had similar experiences?
