Based on what I know about human nature, it is almost impossible for someone to make a big change in their life if their environment does not support it. That goes for anyone and any change but is particularly true for drugs because of the intense pull drugs have on people.
The way to set yourself up for success is to put yourself in a clean environment, however modest, among people who are not using and hopefully among people in recovery.
Some suggestions:
Call women's shelters - if they can't take you they may know about other options
Call the local county economic assistance folks and tell them your problem. Many can give you support to get a job, find a place, etc.
Check into a half-way house for yourself. Most of these require that you have a job and pay a certain amount each month, but there are meetings several times a week, etc.
Go to meetings - often people there have information that you wouldn't have any other way to know about regardng options you might be able to pursue.
I think the one thing you might have to face (hope this isn't too harsh) is that if you are dependent on someone who is dependent on drugs, you can't be free to be your whole healthy self. Getting healthy means becoming 100% responsible for yourself and your life, with or without someone else.
It is better to live modestly with little material possessions than to sacrifice your self, your freedom and your mental health.
Prayers that you find the resources that can put you on the path to joy and freedom.
God Bless
