Angelina, It is not an ideal situation to go forward pro se, but it is your right. First, in general, you cannot be found in contempt of court for failure to pay a debt unless it is willful. If you do not have the ability to pay, then, technically, you're not in contempt. And I say, "technically" because people are found in contempt all the time even though they can't afford to pay.
RULE 12.615 CIVIL CONTEMPT IN SUPPORT MATTERS
(a) Applicability. This rule governs civil contempt proceedings in support matters related to family law cases. The use of civil contempt sanctions under this rule shall be limited to those used to compel compliance with a court order or to compensate a movant for losses sustained as a result of a contemnor's willful failure to comply with a court order. Contempt sanctions intended to punish an offender or to vindicate the authority of the court are criminal in nature and are governed by Florida Rules of Criminal Procedure 3.830 and 3.840.
