If you cannot afford a lawyer, you will have to go to court to represent yourself.  Even though you have been out of work, the judge might impute income to you based on your previous salary.  That means that if you used to earn $30,000 the court may award child support as if you are still making $30,000.  If you will be getting unemployment, then you will have to pay a portion of that as child support.
