"The emotional side of my brain is ridiculously young in a 30 year old's body"
One thing I've heard repeatedly that applies to Me and that I've heard repeated about alcohol use is that we are actually stunting our emotional growth by self medicating emotional pain. In AA circles I've commonly heard that we stop growing emotionally when start drinking heavily and then resume emotional growth working the program. So the sobriety date is considered and 2nd birthday of sorts.
