Blue Novo Nordisk FlexPen insulin pen

I lost my blue Novo Nordisk FlexPen insulin pen yesterday around 3pm near the Starbucks on Main Street in Cape Girardeau, Southeast Missouri. The pen is about the length of a marker, blue body with a white cap, and it has a tiny silver ring around the middle. It came in a gray protective case with a white sticker labeled 'AP' on the outside. This pen is essential for my daily diabetes management and I’m really worried about it turning up somewhere; if anyone finds it, I’d really appreciate getting it back.
