Aw Ready. I don't believe you've lost your sobriety.
You're human. Humans make mistakes. Just don't make the mistake twice. Alcohol has no power over you that you don't give it, but if you give it power it will take everything.
You have a lot on your plate but I've known you 3 years & 4 months & you're perfectly capable of handling all of it soberly & gracefully. Have faith in yourself!
