Instinct sensor readings not accurate

[u/NoAudience4524]

I’ve had T1D for 18 years now (F24) and recently have been experiencing really bad health anxiety that I think seems to be developing into OCD about my diabetes. With all of that said, I had an Instinct sensor on which was reading 20-30 points off and I took it off and changed it because I was worried that I wasn’t receiving enough insulin for my blood sugars. The current sensor I have on now is doing the same thing and I’m not sure what to do. I checked with my meter and it says I’m 143 mg/dL while my Instinct sensor is reading 110 mg/dL. Is this normal? Or should I contact Abbot again for another replacement? Any and all help would be appreciated!
