Please, just tell me what to do

Because I am so afraid of doing the wrong thing, or not acting fast enough, or saying the one wrong thing that creates the horrible opposite outcome of what I'm reaching for. What if I've already said it? What if my phone call is made a day too late? Or even an hour? How would I live with that failure for the rest of my life? I've already been told that I can't shoulder that responsibility, no matter the outcome, and I know logically that that is true, but how logical are we in a tragedy? For the love of Jebus, won't somebody tell me what to do?
