losingit: cog_survivor reminded me of some things. Your local DA's office or City Attorney's office may well have victim advocates to help you through this episode in your life. I worked in domestic violence for a time and learned a lot. There may be a way for you to get money for education or job training (get it from your ex if you can get your attorney to persuade the judge that you need it).
Your children are likely to do what you do. They see what we do much more than they listen to what we say. Think of them when you are behaving in such a submissive and passive manner. Is that what you want them to do? What kind of life do you want for them? The kind you have?
Find out about all the resources there may be available to someone in your situation. Use them to improve your life.
Best wishes,
