When our mind's start to clear by abstaining from alcohol the past becomes more into focus, naturally. Sobriety can be like driving a car at high speed and slamming on the brakes - all the jazzzz in the back seat comes flying forward. We are left to clean up this wreckage.
Early sobriety can be painful. It is the reason we shouldn't not drink alone. The beauty is having this opportunity to reflect, making amends as we should and build on that foundation. Not for self deprecation or regret, but as a fruitful endeavor.
The vast majority of people never do a thorough examination of their lives. In this regard I believe we are privileged as most alcoholics find a self leveling of pride and humility which can be transformational, in my experience.
The key to reflection is understanding not to dwell on yesterday, but learn and move on. It is in the seeking not self pity or wallowing we live productive lives.
