OK, we can't give medical advice here but a concern with high blood sugars is DKA, or diabetic ketoacidosis. This is the UK national health service's take on the subject.

(The UK units for blood sugar are mmol/L and you multiple them by 18 to get your units of mg/dL . 235 is 13.1 mmol/L which is certainly higher than normal but hopefully not catastrophically so. Disclaimer as a T1 my levels go that high far more often than I wish but I can just take insulin to reduce them.)
I don't suppose you have a meter or urine testing strips that test for ketones? DKA requires an immediate trip to hospital, but it is rare in non insulin dependent T2s with your levels and more usually associated with T1s or misdiagnosed T1s. T1 is much rarer than T2 so many adult T1s get misdiagnosed as T2 for the first few years of their diagnosis, until declining insulin levels finally push them into DKA and they get diagnosed via a trip to the er.
I admit to not being very informed about the US health system. Is there a medical line you can phone for advice ?
