Today, ask to be heard. Request the appointment of a legal representative, a lawyer. Request a guardian ad litem for the child or children. That'll generate some discussion, but you say, I didn't learn until this morning, your honor that I could request court appointed counsel.
You'll eventually get a mouthpiece, if your finances are weak enough. If not, you'll be given time to find a lawyer. It'll generate discussion, but you'll get additional time to get yourself a lawyer, assuming you're not poor enough to get a taxpayer people funded lawyer.
