Monthly Bills and Legal Fees

I have been in post separation abuse and endless vexatious litigation for almost 4 years. I have already paid 110,000 in legal fees. I have an outstanding 30k in legal fees. We have at least 3 more hearings coming up that will cost another 20k. My ex is now withholding the court ordered maintenance and child support. I am currently getting a Masters so I can provide for my children with no support but I currently cannot afford my monthly bills and legal fees. Any little bit would help.
