Lots of great responses here, and I would agree that waking up from 2 decades of daily sedation was eye opening and definitely scary for me. It still is scary at times, even several years into being sober.
Along the way I've learned to accept that life is supposed to be scary sometimes...we wouldn't learn to survive if it were easy all the time. Part of life is facing adversity and learning from it.
I've also learned that while we must never forget where we came from, dwelling on the past is counterproductive. And some of the things we would like to "fix" that we've broken simply aren't fixable. The solution is to make today and your sobriety the priority...things around you will take care of themselves for the major most part.
You mentioned in another post earlier that you weren't sure if you needed to get more help...maybe this uneasiness is giving you the answer?
