You should definitely go to the court. Show the judge your financial income & expenditure.The judge will decide what you can afford to pay toward your debt.If you are genuinely in financial distress the judge will only make an order for what you can afford. If you don't show up the judge will assume you are a "wont pay" case and award a much larger monthly payment,or an order for the full amount.Take control of the situation and engage with the court ,it is in your best interest IMO.
This is just my opinion ,not a legal opinion.
