I am going to court for contempt of court for child support

You have two issues that are inextricably tied together.  First, you must file an action to modify your ongoing support obligation.  You will need to be able to show a substantial change in circumstances has occurred since the entry of the support order, and the change warrants a downward modification of your support obligation.  Retroactive downward modifications are granted very rarely, but ending the ongoing accumulation of the support obligation beyond your means is crucial.  Second, you need defend the contempt action utilizing the new action to modify.   Your new action can be used to educate the trial judge at the contempt action of your circumstances, and how those circumstances warrant a finding your action were not “willful” and therefore, not contempt.  Your success in navigating these two issues simultaneously without an experienced attorney familiar with your county’s court staff and judges will be nearly impossible.
