7 days is a miracle! Actually each moment for me is a miracle. Each and every moment I choose to put my attention toward something healthy instead is a miracle that comes from practice.
You may "feel" like you will fail but remember that feelings arent facts, they are just feelings.
For me journaling and telling my story helps keep me sane and keeps me accountable so YAY for you that you want to share, and you never know, you may just help someone who is just sober today.
I wish you the best and congratulations on your new start!!!!
