Dupixent devastations

I was 5 doses going strong with my severe eczema. All of a sudden my dupixent is now a week late going on 2 and i'm devastated to see my skin go right back to how it was, making me want to cry. It was my only hope at a true fix and it was finally working To those that may have had this issue with delivery, what do now? What do when i get my next dose? Treat it as a next dose or a first dose with 2 injections? Any advice welcome
