Welcome to the Talking Sober clan @witchy 
For me, the early days were all about getting to meetings and learning from people who had done it before. There are lists of meeting groups here: Resources for our recovery
There’s a bunch of good podcasts and books there too.
It’s always one day at a time. Don’t fret about the future or dwell on the past. What matters is staying sober now, and reaching out to sober folks to stay in touch (isolation is one factor in addiction).
