What did you lose out on and how did it end? What could you have done better?
I had to deal with a function not in my role, because the person responsible quit. The org was on a hiring freeze so I sucked it up. It was terrible as my goal was not to let the ship sink (that is a terribly low goal to have, frankly, but best under the circumstances). I asked for a pomo (which I believe I will be getting shortly). I also pushed for a new hire to fulfil the function (which has happened now).
So don't just accept shit. My 2 cents.
