My lawyer just dropped my divorce case. My divorce should be final in a month. How can I get the help I need?????

I have left an emotionally abusive husband that has controlled me for years. He has a good lawyer and is very sly. I am scared of him and I am afraid to go into court alone. My lawyer dropped my case because I didn't pay the 2500.00 retainer fee with in a certain time frame. I tried calling my lawyer numerous times and could never get a call back. I one met my lawyer once for a few minutes and that was it. I don't feel like I got any help and my biggest fear is losing my 3 yr old daughter. I have no more money and my ex-husband has his family money. I am lost and scared. We have settled everything as far as custody and property. I just have this feeling when he finds out that I have no lawyer then he will really come after me. Can some one give me advise on what to do?
