Fathers for Equal Rights has a Dallas in office and I think several around the country. There is a membership fee but it is cheap and that is always a good place to start. Some judges hold court in multiple counties and I wonder if the Judge does in yours if you could have it moved to another county same judge. That way you could find legal aid in the other county without spending more money on travel time. Either way I think I would at least call a lawer in a neighboring town and talk to them. I would also think you could get a delay because of your medical issues.
