Picking up the pieces: Single mom of 3

I am a recent single mom of 3 girls ages 9, 2, and 8 months. I have been battling an unpleasant divorce and have been the sole source of income for my girls. I receive no support from their father and I’m trying everything to make sure that they don’t feel the effects of the poor decisions he has and continues to make. As he unfortunately willingly chose alcohol over his family, these are the results of that. I am an RN, however, I’m struggling to stay afloat with bills piling up and being hit with debt that he is equally responsible for. I am trying everything possible to bring in extra income, but as usual there’s always something that happens that sets me back every month. I am asking for help in any way. This is hard for me to go to this length but I need to do so for my girls. Thank you and God Bless.
