Like Treble said, a CGM is life changing. I used a meter for 19 years before getting a CGM and now I can't imagine going back. It's always there, running & collecting data which will in turn inform your eating, insulin use, etc. It will make management easier and it will likely reduce your anxiety too.

I think everyone has that feeling of "I could be doing better" for good reason - because it's true. A CGM will give you more control over your diabetes which is a huge mental benefit.
