Are you talking about worrying?
I have never been in a position to not worry about something. I really think this is a huge by-product of a traumatic upbringing. I do believe that living through trauma for many years rewires your brain, I was told so by one therapist years ago anyway... I too drank to quell the anxieties. They were very real anxieties.
But worrying does provide some productivity because you can at least figure some things out I think.
