Hi Sarah and welcome to SR.
Within week, even days of being sober you will see how much you have been missing with your daughter. And by quitting you are changing her life completely for the better.
You do have a way to go but it sounds like you have some good support and a plan.
We are always here......also keep an open mind about AA. It can work in conjunction with your other support and it will open up opportunities to make friends who will be every step of the way with you.
Take care.
