I am a mom of two little ones as well. It was not easy but when I realized I needed help and then actually got help, things got so much better. My help is the program of AA, a good therapist, taking care of my health. Those people in AA know how to get and stay sober when I hadn't a clue. There are other programs of recovery too should you need help with this.
You're not alone. There are lots of moms here. Just keep coming back.
