Hi and welcome Mr Parker
MLDs covered the science stuff - not everyone gets it, but there is a common experience of anhedonia for a while
I'd also add - for a while I was living my old addicted life - just not drinking - and I was wondering why I was going out of my brain with boredom and dissatisfaction.
My drinking made the intolerable tolerable.
I had to build a new life - a sober life I loved - that takes time too, just like the recuperation in mind and body takes time
You're on the right road - don't doubt that
