Maybe right now, focus on just staying sober. Those unfinished tasks aren't going anywhere. The only task you need to complete right now is your recovery.
When I finally got clean and sober this last time, I realized the extraordinary lengths I would go through to stay high, yet I never applied those efforts into my recovery...until September of 2010. Once recovery was as important to me as maintaining my addiction used to be, I did whatever was needed.
You'll be surprised what you will accomplish as you stay sober. Good luck.
