What a dreadful experience. Heart pounding ... I can imagine all too well.
I have so much trouble keeping on top of things--registrations, renewals. Yours is way worse that any of my failures (didn't renew driver's licence till nearly the due the the
next year, spent my birthday before the judge), or near-failures (almost missed renewing hurricane insurance and we had damage 3 times that year over the deductible).
We're just not good handling this part of life. I'm so sorry. I hope it works out without further complications.
