Great job on 35 days... that is excellent ground. Recovery itself and the brain chemistry balancing and all kinds of stuff can cause feelings of apathy and mood swings by themselves... a lot I think.
One strange thing has been on my mind. It is that sociality. I'm beginning to find that regardless of my previous perception, I'm actually very social in a natural way. And that the anxiety and withdrawing feeling can be the addiction trying to make you miserable. The handicapped part of you that is addicted to that alcohol. Recovery and that in my opinion have together the greatest impact on just about everything in life.
35 days is big. Just keep on...
