Good news, your ready for the next step in your Job.
If it was me, I think you are going to need a few conversations.
Things to understand, the world is changing. How are you on no sleep? Can you really take the step up in this year?
I’d have a chat with the offering company to see how else it could be made to work, or I’d pass it up.
Your ready for it so you’ll get it next time round.
