Congratulations, Nectar. Well done. It sounds like you got this!
I agree with you. When I hear 'I got drunk - I don't know how it happened. It just did', I feel sad. It speaks to a profound lack of mindfulness and self-awareness. A simple moment of self-reflection can be life-changing, if we only allow it to be.
I am really happy to see you post here, and share your story. Welcome! And as dwtb says, Onward! You can do this thing, and having done it, what the heck else can you accomplish?
