Sayang, GDM memang challenging, especially when you're just starting insulin, tapi you're doing the right thing by following your doctor's plan closely. Those readings you're getting are still being monitored by your team every week, so trust the process lah; sometimes it takes a few adjustments to find the right dose, and your doctor will guide you through it. I know the diet control feels so restrictive right now, but a few of my mum friends went through this and they said after the first few weeks, it becomes more normal, you'll learn which foods work for your body. The sadness is real and valid, but you're protecting your baby and yourself, which is the strongest thing you can do. Stay in touch with your doctor's team every review, they're there to help make this easier, okay? You've got this, mama.
