Oh my. You do have a LOT on your plate right now. I’m so sorry you’re not even able to get some sleep tonight. What an incredibly demanding job you have. Don’t feel bad about taking your vacation though. We all need to take breaks once in a while or we completely burn out. These days the workloads are piling higher and higher. It’s hard to balance your work and home life. I hope you get through this soon and that you can catch up on your much needed rest and sleep.
