Welcome Heather

You are showing courage, doing this. Never forget this. You have courage and you are taking action, and that is something to feel good about.
I know it’s hard. I know there’s so much that is unknown and it’s scary as hell. I promise you though: you will figure it out. Keep asking for help and keep connecting with people who can help you, and you will find what you need. Together, you learn to walk your paths 
There are so many good resources to start with. For me, group support made a big difference, and reading about my addiction. There’s good resources for those here
and here
I also find it super helpful to check in here. I don’t do it every day myself (though many people do!), but I do it when I need to get the squirrels out of my head, get them written down so I can see them outside myself, so they don’t drive my crazy:
Checking in daily to maintain focus #42
There are many, many mothers who are in your same shoes. Read around here and you’ll find some, no doubt you will recognize some of your story in theirs. Search “mom” “mothers” “mommy wine culture” “mom guilt” and similar terms (all have been used in threads about this) and you’ll find lots of threads with stories.
You are not alone.
You have the strength and the courage to do this. Take it one day at a time and keep reaching out, keep sharing. You will find your way.
You’re a good person and a good mother, and you deserve a safe, sober life where you can be your full self.
