Fear was a big thing for me too - but the fear I had was always bigger than whatever the eventual outcome was.
I'm not sure it was booze for me - not entirely - because I felt this way from as long as I could remember.
I was both very insecure and yet a control freak - I found it hard to believe things would turn out ok for me, and very hard to let go of outcomes.
the more things I handled sober, the less that fear got - I learned to let go a lot more too
I know this won't work for everyone, but I put my faith in God a few times...thy will be done..and it seemed to work out
