Hi Sara and welcome here,
Your current situations sounds like a lot to handle so you better do it sober 
Hope you will find your way in becoming the best version of you and the best mom you can be, a sober one. Glad you have found us here.
I’m addicted to alcohol and mom of 3 who are very glad I quit drinking. My life is so much better now, I wish you the same.
You already have had some threads to read and I would like to add two myself.
What's YOUR plan? The first one explaines the need of a plan as well the stages if recovery. The last one is the thread I made at my 2 year sober milestone and maybe give you some practical tips too:
2 years sober and what helped me to get there: I’m still sober since september 2018.
So again welcome Sara, if you have any questions feel free to ask!
See you around!
Claudia
